RE: Rad Worker Layoff??

Be careful about sending workers back into areas that require frisking for

contamination.  Some of radionuclides have low levels of contaminates that

may remain in the active even after the primary imaging radionuclide has

decayed away.  For example Tl-210 has a half life of 73.1 hours.  However,

the trace contaminate Tl-202 has a half life of 12.0 days.  The dose to a

dosimeter would be trivial, but I would scan every worker who has undergone

a nuclear medicine procedure before allowing them to go through a portal

monitor.

Tom:



Since most medical radionuclides have a short effective half life, I believe

that the person would be unable to wear a TLD only for a relatively short

time.  Therefore the employer might have to make a case for hardship, or the

employee might have a case under the ADA (Americans with Disabilities Act).





The employee's case might be further strengthened if the TLD is not really

required for te job (ie, 10% dose limit expected to be received).
