@Majj it is worthy of being mad about. :-)

Good morning, I guess iodine and cesium are the frontrunners because they are the prevalent radionuclides emitted. Strontium would be easy to detect because it is a gamma emitter. Alpha emitters are difficult because of the short travelling range of the particles. They must take soil samples to detect them, and it is enigmatic to me that they even find anything without a hint where to look.

I strongly believe in the sensitivity of bioassays. If they thoroughly analyzed all kinds of organisms, us included (peep and poop), for radioactive metabolites, they would get a much more complete picture of the extent of the contamination.

@ElaineKirk working on the ICRP story today (finally :-) ) planning on running it tomorrow morning. I have the background info you sent me, a guardian article questioning their standard and their funding sources. Did you have anything new that should go in there?
by lillymunster 8/23/2011 1:44:23 PM

@lillymunster I will be home in a couple of hours I will do a 'past week' search and let you have anyhing new :)

@lillymunster there was absolutely mo news anywhere this morning before I came out but the billions the red cross are not going to give to the people of fuku was causing a lot of comment on twitter, those donations should hae been given to or used for the people months ago

If anyone is looking for a Geiger and does not mind a somewhat antiquated alarmist look, this Victoreen CDV-700 civil defense issue from the sixties seems perfectly adequate: thumbs3.ebaystatic.com . This country is still home to thousands of them. They work well for beta and gamma radiation. An easy way to check whether the instrument still works when you find one at a yard sale is to put a pack of Coleman gas lantern replacement sleeves (socks? do no the right term) in front of the detector.
by Peter Melzer via Thumbs3.ebaystatic 8/23/2011 2:09:53 PM

@you , do no = do not know, ;)
by Peter Melzer 8/23/2011 2:11:17 PM

@Peter Melzer what are the lantern sleeves made out of? I had been thinking about buying one but didn't know how to calibrate it or test it to make sure it was reading right...
by lillymunster 8/23/2011 2:12:50 PM

@lillymunster , they contain Radon (interesting eh?).
by Peter Melzer 8/23/2011 2:13:49 PM

@Peter Melzer lol. Do these need calibration of some kind or just run them against a known source like the sleeves to see if it reads?
by lillymunster 8/23/2011 2:14:41 PM

@lillymunster Any instrument must be calibrated at times, otherwise it will show inaccurate readings.
by Pedro Jesus 8/23/2011 2:16:33 PM

@lillymunster , yes of course. And lilly this is a good question, because certified services were set up in this country where you were supposed to send your Geiger periodically for calibration. I wonder whether those still exist.
by Peter Melzer 8/23/2011 2:18:10 PM

@lillymunster , the sleeve test tells you only whether the instrument is still in working order.
by Peter Melzer 8/23/2011 2:19:05 PM

The nice thing about such instruments is that they are rugged and simple. You calibrate them by setting a known source at a prescribed distance in front of them and adjusting the meter hand to the value of the source with a screwdriver. With today's high tech gadgets the process is much more opaque.
by Peter Melzer 8/23/2011 2:23:21 PM

I suggest you use it only at home. Imagine you walked your local Saturday farmer's market with this gadget in hand waving the probe around! That would probably get you arrested for disturbing the peace or something.
by Peter Melzer 8/23/2011 2:28:16 PM

Coming to think of it, possibly you could place the Coleman sleeves in an airtight box together with the detector and a household radon testing kit (activated carbon filter) and use the result of the test to set the meter. Might work.
by Peter Melzer 8/23/2011 2:36:04 PM

@Peter Melzer I see them on ebay frequently and many put the caveat that they don't know if they are properly calibrated. If I could find someone capable of calibrating it I would be inclined to pick one up. Using one at a farmers market would likely induce panic, even more so if you picked up a tyvek suit at the hardware store on the way. :-)

I want to go out to the old Pathfinder site and take readings..
by lillymunster 8/23/2011 2:40:53 PM

@lillymunster , I let you know when I find something. At universities the radiation safety depts provide this service for the labs that work with radioactive material and are required to have a dose meter. I found the pic of the instrument on ebay. The high priced ones are supposedly calibrated. So these services must still exist. Somebody figured an iphone app that digitizes audio monitor clicks and converts them into graphs and such: itunes.apple.com

by Pedro Jesus 8/23/2011 3:20:14 PM

@lillymunster , well, I would not want be in there for a minute. Must be like getting a silent MRI. But I think their calibration services are worth a consideration. Pedro, I have no idea. Just found this product advertised on the site I provided the link for for GM calibration.
by Peter Melzer 8/23/2011 3:21:32 PM

@Peter Melzer I got stuffed head first into one of the old school MRI units. Had a major case of claustrophobia ever since.
by lillymunster 8/23/2011 3:27:26 PM

The company has good pictures of the calibration process on the site. The source is installed in a shielded box which is designed to accept certain Geiger models so that the good people working on calibrations all day do not get exposed too much.
by Peter Melzer 8/23/2011 3:27:56 PM

@lillymunster , I once spent 90 minutes in one of those tunnels for a research study. It was so boring, I began to count the grains in the tunnel cladding until I fell asleep. It was a brain study. The scientist's measurements dropped and he came running to check whether I was still alive.

@Peter Melzer When my father was in the navy back in the late 60s he did the sub test, which was compulsory at the time. It was meant to test your ability to work in submarines, although we didn't have any at the time. Weird. I can't remember how long you had to stay in the tank but my father just found it boring. Nothing to do in there.

lilly, if you seriously wish to buy one, buy the model I posted below. Victoreen used to be a leading company in the field. Also the instrument should have detachable probe. The ones with probe built in are as sensitive. Some probes allow adjustments to separate gamma- and beta-measurements. They feature slits on the side that must be opened for beta-counting. This is the probe you want.
by Peter Melzer 8/23/2011 3:37:45 PM

@estacion any reports on the dam?
by lillymunster 8/23/2011 3:44:00 PM

Pedro, that was my experience as well. On top, this scanner made a very repetitive noise a bit like a pneumatic drill. I had ear plugs. Hence it was not loud, but it was always the same and really wore me out. But I do understand people getting anxious in there. In addition, one must lie very still for head scans. Later I led a study using this technology and made a point staying at the bore that my people could see me during the study. I may have lost a bit of hearing with that because the noise is very loud outside the tunnel. But it was important to me to keep in touch with my people.
by Peter Melzer 8/23/2011 3:44:15 PM

@Peter, we looked at buying an old Victoreen before Fuku. We have lots of old odd antiques and old military stuff.
