Really great stuff! 18:22:26 From Peter KX4LB : Thanks!!! 18:32:34 From Jeffrey Rodgers : We are building a shelter right now. The shelter is not going to be ideal due to financial and building code constraints. It will be a 16 foot by 15 foot concrete block shelter. The entrance will be 3 feet hall with a 90 degree angle then the stairs to the surface. The entry door is going to be a heavy duty security door. Do you think putting concrete blocks into the hall would be necessary to increase pf? The shelter will have 4 feet of dirt 18:35:06 From TACDA : We'll see if Sharon can answer that question when she is through. 18:38:06 From Peter KX4LB : If that lithium battery gets wet and starts a fire, you're done! Especially in the confined space of a shelter! 18:38:56 From Peter KX4LB : We built our shelter from an old underground fuel storage tank 18:43:02 From Mike Weber : Replying to "We built our shelter..." Where did you get the tank? Diameter/length? 18:43:51 From Charles : Could I watch this again later? If so, how? 18:44:25 From tstump : Replying to "Could I watch this a..." youtube 18:44:44 From Peter KX4LB : Replying to "We built our shelter..." Ebay. 8'x28' 18:45:00 From TACDA : Replying to "Could I watch this a..." It will be posted later on our website with a link to watch it on YouTube. 18:45:02 From Tobin Gardner : What is the average pricing on things like this? 18:45:04 From Bruce Curley : Replying to "We built our shelter..." It will be uploaded to the TACDA website 18:45:10 From Mike Weber : Replying to "We built our shelter..." Didn't think of ebay for stuff like that 18:45:14 From Mark R : Doesnt having the air filter in the shelter mean you would get irradiated by fallout filtered? 18:46:06 From Mike Weber : Replying to "We built our shelter..." How did you clean out the fuel smell/residue? 18:46:46 From Peter KX4LB : Replying to "We built our shelter..." It came already huffed 18:46:48 From DOUGLAS CLARK : We did a docent tour of the Sonneberg Bunker. In Lucernce. It was at one time the worlds largest civilian chatler. 18:47:20 From DOUGLAS CLARK : Sorry for typos, Lucerne, Sonnenberg Bunker 18:47:20 From SCB : Median cost of 10 ft x 50 ft corrugated steel pipe shelter, with only the basic necessities, approx 25 miles from potential blast zone? 18:47:51 From Prince Stephen : There’s an active shelter in Portland I believe 18:48:10 From Peter KX4LB : Sharon, my wife says you're so nice! ❤️ 18:48:29 From Gatlin : I have two questions: How long would alpha particles linger after nuclear war and should people shelter in place or evacuate if a commercial nuclear power plant had a disaster? 18:49:00 From Matt Kromke, P.E. : Have you ever considered oval corrugated pipe? 18:49:33 From Prince Stephen : Do shelters need to be underground? I live in Houston and we’re very close to sea level. 18:50:35 From Richard Goetz : How do you hold this together against the seismic effect of the nuclear blast? 18:50:37 From Bruce Curley : https://www.repurposedmaterialsinc.com/ for inexpensive materials to build a shelter 18:50:57 From Mike Weber : Replying to "We built our shelter..." Are you a ham? 18:51:10 From Mike Weber : Replying to "We built our shelter..." WE0BER here 18:51:15 From Webb : SOME concrete pipe is reinforced. It is designed for under roadways. 18:51:29 From tsorr : <<< KQ4CLU 18:51:51 From Tobin Gardner : Replying to "We built our shelter..." @Mike Weber K7TOB here. 18:52:07 From SCB : What are necessary basic add-ons for poured reinforced basement (9’ high walls, 8” thick walls below grade), built under a 2-story house with a large attic space above…30 miles from potential target/blast zone, mainly concerned about fallout. 18:52:16 From George : what is the distance from ground zero in your shelter examples? 18:52:36 From Mike Weber : Replying to "We built our shelter..." Lots of hams in the preparedness world 18:53:05 From John Molinaro : Thank you very much for the information! 18:53:16 From DOUGLAS CLARK : My concern with metal shelters is dew point condensation during times of habitation. Dew point calculators shows at 75 degrees 55% humidity steel shelter at 57 degrees WILL condensate. We have been to shelters with ponding due to condensation. 18:53:58 From Bruce Curley : Replying to "We built our shelter..." TACDA website and Journal of Civil Defense have lots of ham radio info 18:54:36 From DOUGLAS CLARK : Condensation will result in mold. Indoor air quality issue health hazard. This will not occur until occupants care the humidity. So empty they could be ok for decades. 18:54:37 From Peter KX4LB : Replying to "We built our shelter..." Yes I am!

I Have some apple pectin as well. Do you think this is useful? 18:56:27 From Steve McAtee NØJJO : I recently saw mentioned that for people over age 60 taking iodine after an event is not needed. Any comments on that? 18:57:27 From Peter KX4LB : Does it need to be planted at a certain depth to protect the root vegetables from fallout? 18:57:29 From DOUGLAS CLARK : Typo. should be “ until occupants cause humidity” not “care” -sorry 18:58:46 From DOUGLAS CLARK : Question: 18:59:15 From SCB : What are necessary basic add-ons for poured reinforced concrete basement (9’ high walls, 8” thick walls below grade), built under a 2-story house with a large attic space above as 3rd floor…hardwood floors directly above basement…30 miles from potential target/blast zone, mainly concerned about fallout. 19:00:16 From Gatlin : Awesome! Thank you so much! I'll definitely look into the iodine. 19:00:42 From DOUGLAS CLARK : For large and long term shelters, what is code or sensible guidelines for living space per occupant. There is dispute on this and code is scant on this occupancy type. So for professional architects, can you cite code to except projects form code for habitable rooms 19:01:34 From Shane : If you have been in your shelter for two weeks, how do you know that another attack has happend and new fallout has occured? How do you know when its safe? 19:01:38 From Tim Taylor’s iPhone4S : I built several Keerny Fallout Meters using Cold War instruction Manuals. They take some effort to build, but they seem to work as advertised. 19:02:21 From DOUGLAS CLARK : For above ground shelters, d if not space for 30 degree slope also consider double wall system . Two concrete walls with gravel between, but its the inner walls that Neds water proofing AND drainage between the walls. 19:04:48 From Stephen B. : Would rather be uncomfortable than dead 19:06:35 From Peter KX4LB : Does mylar insulation offer thermal protection? 19:06:47 From Richard Goetz : IT seems like the heavier equipment (i.e. water tanks, generators, fuel tanks, etc) should be suspended from the cieling to keep them from damaging/breaching the containment enclosure. Attaching them to the floor will rip that shelter to shreds in the initial nuclear event. 19:08:27 From SCB : What are necessary basic add-ons for poured reinforced basement (9’ high walls, 8” thick walls below grade), built under a 2-story house with a large attic space above…30 miles from potential target/blast zone, mainly concerned about fallout. 19:08:28 From Richard Goetz : Is the support equipment in a separate underground enclosure? 19:08:37 From Hakima Robinson-Rashad : Apple pectin is better if your over 60 and for small children. They learned this from Russia. 19:08:42 From Tobin Gardner : If you had to guess, what percentage of Utahns have shelters like this? Seems like 75% of people aren’t even thinking about food storage. 19:08:53 From Stephen B. : How well do modern day houses stand up to nuclear attacks? 19:10:55 From Peter KX4LB : I've noticed that the locker rooms at my YMCA would make great fallout shelters! They even have 90° turns on the entrance and they're below ground! 19:11:25 From SCB : Reacted to "I've noticed that th..." with 👍 19:12:19 From Stephen B. : What’s the best filters for ventilation? Potassium absorbers? 19:13:29 From Peter KX4LB : Project "Greek Island 19:13:48 From Stephen B. : Oh good 19:15:16 From Stephen B. : Thanks for y’all’s time today 19:15:18 From Robert Hagler : Thank you 19:15:20 From M Poling : THANK YOU! GREAT PRESENTATION!!!!!! 19:15:29 From Gatlin : Great stream! 19:15:36 From Robert Dorn : Thank you! 19:15:48 From francisco : thank you.
