[ RadSafe ] Determining Radon

[Nardi, A. Joseph]

One interesting technique I saw was to use "Saran Wrap" in bulk rolls.  If
you pull off a large piece it will pick up a static charge.  Then pass it
over the contaminated clothing and it will pick up the contamination,
particularly radon daughters.  This does not solve the instrument detection
issues but it allows you to release the individual faster.

Subject: [ RadSafe ] Determining Radon


Our soil remediation project just acquired a PCM-2.  This is a whole body
gas proportional frisker set up to detect alpha and beta contamination.
Since we are a soil remediation project, we are subject to radon gas. Per
our procedures, we are required to report all personal skin and clothing
contaminations with the exception of contamination due to radon gas.  I was
wondering if anyone out there has had experience with this type of
instrument in detecting radon gas and what methodology is used in the field
to determine if the alarms are due to radon or real contamination?  Please
keep in mind that we do not have a count room available with the gamma spec.
capabilities.  We are limited to field instruments only.  

Thank you in advance for all replies to this inquiry.
