You won't detect radiation from Japan in the U.S. with old Civil Defense Radiation Detectors

PLEASE READ! Here's a semi-coherent attempt I made to describe the old Civil Defense Geiger counters that are now selling on ebay for ridiculous prices. You won't be able to detect the very slight radiation that might make it here from Japan with these old detectors. I try to explain that in the video. Hope it makes sense. The old civil defense high-range detectors CD V-710, CD V-715, CD V-717, CD V-720s are very high range gamma radiation detectors. They ARE NOT Geiger Counters as they are being called on ebay. These high-range detectors were designed to detect levels of radiation hundreds of times higher than a geiger counter. Please don't waste your money on one thinking you'll be able to detect radiation from Japan in the United States with these. Also any radiation that might make it to the U.S. will be so diluted that the CD V-700 Geiger Counters most likely will not detect it either. If you do get a geiger counter keep in mind that there is background radiation everywhere. Just because you get a slight reading doesn't mean it's radiation from the nuclear plant in Japan.

Man, I love your website. Really hate how that whole japanese radiation thing has put a damper on my collecting. I collect cold war era relics (gas masks, geiger counters, the whole 9 yards)

and its just awful how pricey some of the stuff that can't even help people is. Also, may I ask why some of the docimeters I have are yellow and some are like a copper color without paint? Which is rarer?

cheers

@galacnor The Landsverks were the ones with the gold finish. I guess they were close to the yellow so they didn't have to paint them. The Bendix CD dosimeters were painted. I have seen a few painted yellow landsverks though. Mostly the earlier verision CD V-730/740ish Landsverks were painted. I guess the landsverk anodized dosimeters are the fewer of the CD dosimeter models. I remember some mention that the landverk CD dosimeters were the least reliable. Can't remember who said that though.

Why did thyroid cancer spike to epidemic levels? A prominent doctor from Indiana said his case rate went for 3 case per month to 3 cases per week. i guess we need to be careful what we eat.

@mechanicalbu11 What are you talking about?

Thank you for making this video. Saved me from buying a practically useless device. I owe you a beer.

@galacnor cash in brah! You won lotto

@cautionthisissparta Actually, I meant new manufactured instruments. I have a nice CD V700, a couple 715's, and some dosimeters and chargers, but I'd like some new ones for both high and low levels.

@Wyowanderer777 Both the 700 and the 715 are decent, and they bring back memories

A few years ago we cleaned out our crawl space in our old Fire Station. We came across like 30 boxes of items like these. Each box came with three units and about 5 dosimeters.

You mentioned in your video about calibrating the units I live in Massachusetts, do you know of any reliable places to send what we have to be checked?

Excellent video, thoroughly explains the difference between a geiger counter and survey meter.

Any suggestions for a good geiger counter and a good survey meter?
