I just did the worst case scenario calculations (which is impossible to happen since most of the canisters were used in homes and not in underground caves), which would be to assume that in the place where the 200 canisters were located there were 1000 Bq/m³ = 1KBq/m³ If we take into account the...

I wrote to 'Health Physics Society' about this matter, and that's what they answered me by email:

My boss, who is a nuclear physicist in the nuclear physics department, told the lab technician that there was no danger and that there was no need to report it to the university's health department. This is what the technician told me. Actually there is no RSO at this university, but there is a...

Hi everybody and thank you for your replies. The temperature at which I had to set the oven was 180 ºC, and some of the canisters were used to measure radon gas concentrations inside underground caves. The canisters were left to rest, but they were all sealed with insulating tape, for over a...

The university's safety department had no knowledge of what was going on there. I guess the reason is that my boss didn't give them any information.

The lab actually belongs to a university, and they had never done radon measurements before. The 200 canisters that I heated in the oven, which they bought new for the occasion, were the first canisters they had ever measured radon with. The detector they used to measure the activity of the...

Hello everybody! I am writing to you because I am worried with the content of radon progeny inside standard activated charcoal canisters used for radon measurements. In 2011 I was working in a laboratory that was measuring radon with activated charcoal canisters, and they bought an oven that I...
