AW: [ RadSafe ] Determining Radon

[Franz Schönhofer]

How is this calibrated???????

I put out on RADSAFE a lot of questions, the answers to which would have
been necessary to give some explanations or advices, which I was willing
to give. I (or RADSAFE) never received an answer, which seems to me a
confirmation that the original question was put by somebody, who had no
idea about what he was asking about. 

I wonder what the license criteria are for health physicists who should
supervise such operations. 

Of course it is much easier to flame somebody who demands additional
information for advice than to give the parameters which are necessary
to judge a special situation.
