1963 Fallout Shelter Occupancy Experiment

falloutblastshelter

This diagram shows a prototype blast and fallout shelter constructed in 1961 at the National Naval Medical Center, now known as Walter Reed National Military Medical Centerin Bethesda, Maryland. It was used in various occupancy studies in which test subjects were housed in the shelter for various lengths of time. However, all of those studies were flawed in one respect: In a real attack, people need to go to the shelter with little if any advance notice or preparation. This condition is very hard to duplicate in a research experiment. It’s necessary to tell people in advance about the experiment in order to get their consent. So in 1963, the Navy came up with a test that would duplicate, as much as possible, the surprise factor inherent in a real emergency situation.

To conduct the test, the Navy recruited Naval Reserve Officers to participate in a seminar, ostensibly to last two weeks, involving lectures and field trips. They were told to bring work clothing, and because there would be extensive field trips, they were told not to bring their families or make plans for social engagements. The seminar would satisfy their two-week training obligation.

34 Officers volunteered, and attended a lecture the first morning. After lunch, they went on their first “field trip,” to the shelter shown here. After a tour, the seminar organizers made a presentation on the necessity of a realistic simulation of emergency occupancy. With no further ado, the group was requested to volunteer to remain in the shelter for an indefinite period. There was “no question that the participants were taken completely by surprise whn they were requested to remain in the shelter. Their faces betrayed a moment of disbelief followed immediately by the cooperative acceptance of an unexpected situation for which Naval officers are trained.”

The officers were informed that continued participation was completely voluntary. Only one officer departed at that time, since he was a University professor who was obligated to write some final examination questions. However, after he wrote his questions and mailed them to his school, he returned to the shelter the same day as a “casualty.”

The participants spent the next several days susbsisting on rations, taking simulated radiation measurements to estimate their departure time, and generally performing the tasks necessary for shelter occupancy. Because most of the officers had an engineering background, they were also tasked with making recommendations for improvements to the shelter.

The report of the experiment is available at the Defense Technical Information Center and contains numerous recommendations from the participants.

The participants’ reactions to the experiment were in four categories, of approximately equal numbers. One group viewed the experience as an interesting challenge and opportunity. Another group reacted with immediate and surprised anger at being “exploited,” even though they were still willing to volunteer. A few bordered on belligerence. Another group was initially unhappy and eventually either withdrew or became minimally cooperative. The natural leaders of the group emerged from those who viewed the experiment as a challenge, as well as among those who initially felt “exploited.”

Rations consisted mostly of survival biscuits, supplemented with tomato soup, peanut butter, and jelly. Coffee was provided, along with sugar and coffee creamer. The average calorie consumption was 1414 calories per day and the men experienced an average weight loss of 1.1 kg.

After 4-1/2 days, the simulated radiation levels had dropped to safe levels, and the confinement in the shelter ended.

I now have available on my website a complete scan of the 1962 Civil Defense Operational and Survival Plan of the City of St. Paul, Minnesota.  This 104 page document goes into great detail as to how the city planned to survive the aftermath of a nuclear attack.  Of particular interest is the complete handbook for managers of public shelters.  The handbook would give the fallout shelter guidance on all aspects of operating the shelter.  There is some information in this document of practical guidance.  For example, the section on radiological defense contains some useful information.  However, the document’s main interest is as a fascinating historical look at civil defense plans fifty years ago.

Seventy-five years ago today, September 18, 1939, Life Magazine carried this illustration from the British Home Office showing a basement room equipped and gasproofed. The caption notes that if the occupants remain quiet, there will be enough oxygen in the sealed room to accommodate five persons for twelve hours.

Civil Defense Postattack Broadcast Planning: 1963

1962XtalSets

In an earlier post, we looked at how the Defense Civil Preparedness Agency had been planning for emergency broadcast antennas in 1973. The agency and its predecessors had long recognized the need for dissemination of information by radio, and had commissioned a number of studies on the subject. One which took a comprehensive look at the subject was conducted by Technical Operations Incorporated of Burlington Massachusetts. The study culminated in a report issued on 7 January 1963, entitled “The Civil Defense Role of Radio Broadcasting in the Postattack Period.”

The report began by identifying three distinct phases of the postattack period. The first was the Buttoned-Up Period, during which time the population would be confined to shelter because of high radiation levels or because further attack was anticipated. This would be followed by the Emergence Period when some outside exposure would be possible. At such time as a full workday was possible outside of the shelter, the Recovery Period would begin and recovery would be the focus of the public’s activities. Each of these time periods had distinct requirements with respect to broadcasting, and the report then moved on to discuss the numerous broadcast needs.

The first broadcast information discussed related to fallout, which would need to be broadcast frequently during the Buttoned-Up Period to facilitate planning by shelterees. In addition to general forecasts, these would include warnings of local hot spots, instructions on methods of decontamination and identification of safe foods, and information on the length of time over which shelter supplies would need to be rationed.

Broadcasts would also need to convey a large amount of information as to how the public could access emergency services, and would also serve a role in alerting those furnishing those services. Locations of food and water supplies could be broadcast, along with admonitions to avoid hoarding of those limited supplies. Locations of emergency hospitals and medical supplies could be broadcast, along with pleas for blood donors and volunteers to staff the hospitals. Information as to sources of fuel and power could be broadcast. And if the electrical mains were operative, the instructions might include rationing instructions. If fires were burning out of control, the broadcasts might include calls for volunteers to assist in their control, as well as warnings of fires close to particular shelters.

Much educational programming would be necessary. In addition to broadcasts of food decontamination methods, emergency first aid instructions would need to be broadcast during the Buttoned-Up Period, since no outside medical aid would be available at that time. Since some shelters might be stocked with radiological instruments with no trained personnel, this training could be broadcast as well, along with training on sanitation, shelter management, rationing of supplies, and even disposal of the dead.

During the Recovery Period, a very high civil defense priority would be re-establishment of public transportation. Once again, broadcasting would play an important role, since it could be used to call drivers back to work, as well as to announce schedules.

Even apart from this vital information, radio would be important to the public morale. The report stressed the importance of morale-boosting messages from the President, as well as by state and local leaders. Similarly, to stop the spread of rumors and boost morale, it was deemed important to broadcast news of the attack and counterattack. This would also prepare the people for the conditions they would face upon emergence, and also instill a feeling in the people that this was not a personal disaster, but that the whole population of the nation was included. The report noted that good news is always best, but that even bad news is superior to no news at all, since it helps define the environment and diminish uncertainty. The report noted that any unaffected regions of the country should be kept up to date, in order to properly tailor relief and rescue operations.

Broadcasts should frequently give the time and date, since in such emergencies, people frequently lose track. In addition, program schedules should be announced, in order to facilitate conservation of scarce batteries.

Broadcasting could also play a role to re-establish normal commerce during the Recovery Period. Even during the Buttoned-Up Period, the report recommends that people be informed as to the rules and regulations over such things as “whether the needy will be allowed to take what they require without being charged with illegal looting.”

Radio would also play a role in the care of displaced persons, since stations could broadcast information to reunite families who were separated at the time of the attack. These broadcasts would include locations of camps, shelters, and displaced person centers. In addition, during the nighttime hours, lists of people safe in various shelters could be broadcast for the benefit of their families in other areas.

Evacuation instructions and warnings of another attack would obviously have a high priority for broadcast.

The report notes that broadcast stations would undoubtedly be used to call civil defense personnel and members of the National Guard to duty and provide some instructions. Broadcast stations could even be used to relay civil defense messages from one area to another. The nighttime hours, in particular, might be put to use relaying such official messages, and civil defense officials in other areas could be assigned to monitor broadcasts from neighboring areas.

Finally, the report recommends that some entertainment should be furnished, particularly during the time in which people are in shelters. It notes that “music properly chosen many substantially aid morale in the rebuilding phase.” The report warned, however, that people with battery-operated radios should be advised to conserve batteries by listening to only a minimum amount of non-essential programming.

The overall contents of the broadcast day of a typical local station are shown in this chart:

CDbroadcastday

After identifying all of these needs, the report goes on to a discussion of how these needs can be satisfied. While some other options (such as public address systems) are briefly discussed, the only reasonable method of addressing these needs was with standard AM broadcasts. Virtually all American households had a radio receiver, and a large number had a battery-operated set. The report even notes that “for the really economy-minded, there are crystal sets selling for as little as $1.49,” which would be suitable for receiving local stations with no batteries, but with adequate antenna and ground. The footnote for this assertion is to the Radio Shack catalog, and the price obviously refers to the “Rocket Radio” shown at the top in the illustration at the top of this post.

The report did address many of the practical issues confronting broadcasting in the post-attack environment. Presumably, most information would originate at the civil defense Emergency Operations Center (EOC), and links would be necessary to studios or, preferrably, direct to the transmitter site. Since telephone lines would be vulnerable, mobile broadcast units would be advisable, although the report toyed with the idea of installing AM transmitters directly at the EOC, or the use of mobile or even airborne transmitters. Protection of station staff and equipment was addressed in this and other studies.

The report lamented the fact that the radio industry, even though some personnel served on relevant civil defense committees, largely lacked civil defense plans. For example, even radio station switchboards were poorly suited for civil defense needs. As addressed in my earlier post, vulnerability of transmitter towers to blast damage was a very big issue, as was fallout sheltering for station staff.

Station power was discussed, although the report noted that some stations already had emergency generator capability.

At the time of this report, public shelters were not stockpiled with radio receivers, and the report noted that this oversight should be rectified. This, of course, was never done, apparently the planners going along with the reasoning, “surely some people will bring radios to the shelter.”



 

Civil Defense Emergency Antenna Instructions, 1973

ExpedientHorizontalWire

In 1973, the Defense Civil Preparedness Agency was grappling with the issue of how to keep broadcast stations on the air after a disaster, presumably up to and including nuclear war. It was recognized that a station’s weakest link was its antenna. While most antennas are designed to survive normal environmental disturbances, they are the most exposed element of a station and could be destroyed by extreme disturbances. Therefore, the agency commissioned a study on the subject, the final report of which is available online.

In the report, the engineers propose that expedient antenna kits be supplied to stations, and proposed instructions are included. The report proposed kits for both AM and FM stations, along with instructions for station personnel to deploy them. The cost of the expedient AM antenna kit, a quarter-wave horizontal wire, would be $425.37. The expedient FM antenna kit would be about $1000. Both antennas would require installation at the station, prior to the disaster, the necessary utility poles that would support the antennas.

Recognizing, however, that the government might not want to bear this expense, the report also includes instructions for station personnel to construct an AM antenna using available materials. Once again, the recommended antenna is a horizontal wire, either the length of the destroyed tower or a quarter wavelength. The diagram of the recommended antenna is shown above.

Ideally, the feed point of the emergency antenna would be at the base of the fallen tower, but other options are discussed. A last resort, if the feed line were destroyed, would be to put the feed point of the antenna directly at the transmitter. The instructions caution that “it is possible to construct a transmission line, but don’t try. The performance of an antenna fed at a transmitter without a good ground will probably be better than the performance with a good ground and an improvised transmission line.”

These instructions also presuppose that the utility poles were never installed prior to the disaster. Instead, it advises to use “any existing structures available such as trees, buildings, and utility poles. A step ladder or even an automobile can be used if nothing else is available.”

Improvised antenna insulators.

Since antenna insulators probably aren’t on hand, the instructions suggest some possibilities, shown here, using things that might be found around the radio station, such as the soft drink bottle.

The main idea was to get back on the air as soon as possible. “Time is more important than radiated power, so an inefficient operation in 15 minutes is better than full power in two hours.”

 



Expedient Winter Shoes from Newspaper

Even if you’re not contemplating a nuclear war, the book Nuclear War Survival Skills by Cresson H. Kearney is chock full of interesting information.  This book is freely available at various sites, including the Google Books link above.  It is based on research done by the author while employed at the Oak Ridge National Laboratories, and was published and placed in the public domain after his retirement.

One of the items that I’ve always found intriguing is the description of homemade winter boots found in Chapter 15.  Here are Kearney’s instructions for making boots from newspaper:

IMPROVISED WINTER FOOTWEAR

Cold-weather footwear that is warmer than all but the best-insulated winter boots can be improvised readily. The trick is learning how to tie the several insulating layers securely in place, so that you could hike for miles in the snow if necessary.

For use in dry snow, first tie a porous insulating layer—such as two bath towels or 10 big sheets of newspaper -over each shoe. If you have no lowheeled shoes, make a paper sole by folding 3 large newspaper sheets to make a sole that has 72 thicknesses of paper. Then proceed in the following manner:

1. Place your foot and the sole on 10 newspaper sheets, as pictured in Fig. 15.5.

KearneyFig155a

Fig. 15.5. Insulating a foot with a folded newspaper sole and 10 sheets of newspaper.

2. Fold all the sheets over the top of your foot while keeping the sole in the proper place, as indicated in Fig. 15.5.

3. Use a strip of cloth about 3 inches wide and 5 feet long to tie the papers in front of your ankle with a single overhand knot (half of a square knot). With the same strip, tie another single overhand knot over the tendon behind the ankle. Finally, tie a bow knot in front of the ankle.

4. Cover the insulating layer with a tough fabric, such as canvas or burlap sack material; secure with a second strip of cloth and tie as described above.

KearneyFig156If the snow is wet, place a piece of strong plastic film or coated fabric outside the insulating layer, after securing it with the first strip of cloth. The outer protective covering should be tied over the waterproofing, with the second strip of cloth securing both it and the waterproofing. (When resting or sleeping in a dry place, remove any moistureproof layer in the foot coverings, to let your feet dry.) Figure 15.6 shows a test subject’s waterproofed expedient footcovering, held in place as described above, after a 2-mile hike in wet snow. His feet were warm, and he had not stopped to tighten or adjust the cloth strips.

20140105_144109Since the temperature this afternoon was about -10 degrees Fahrenheit, it seemed like an ideal day to test this expedient footwear.  Since I was using it for only a short test close to home, I didn’t bother using the full ten sheets of newspaper called for by Kearney’s design.  Instead, I started with a sole

20140105_144144made of corrugated cardboard, and used only about three sheets of newspaper.  I then tied these as indicated in Kearney’s instructions.  I finished by covering them with a plastic grocery bag.

The completed shoes.

The completed shoes were surprisingly comfortable, and they also kept me surprisingly warm and dry as I walked around for a few minutes outside.  I was able to walk quite comfortably through a snowbank.

With the very thin insulating layer, I’m sure that my feet would have gotten cold eventually.  But the concept obviously works, and with more insulation, I think I could have stayed outside indefinitely.

Also, in a true survival situation, I would want to have the waterproof layer by considerably more durable than the thin grocery bags I used.  Eventually, the thin plastic would have torn, my feet would have gotten wet, and I would be in a lot of trouble.  But for my short venture outside, these proved perfectly adequate.

Of course, after seeing me test these, my kids wanted to give it a try themselves, and they both made themselves a set of emergency winter boots.  So yes, I allowed my kids to go outside without shoes with the temperature of ten below zero.
