Fw: Epidemiological evidence of lung cancer risk

["jenday1" <jenday1@EMAIL.MSN.COM>]

Mike,

Thanks for the information.  In nuclear medicine, the use of noble gases is

only a small number of studies performed, and consequential a small faction

of the dose received by the technicians.  The vast majority of the dose is

from studies involving the injection of Tc-99m compounds.



For background information, I would appreciate a copy of your paper, or a

reference to it.

I should have commented earlier, but John has reminded me of this question.



One way to "monitor" for potential internal doses to these noble gases would

be to use a standard personnel contamination monitor, e.g., PCM-2.  Last

year, I had many requests for my paper on noble gas retention in body fat.

The concept is that very small doses can be measured through whole body

counting, or even the use of a PCM.  You could prove that your staff is

incurring very little dose each day if they can pass the monitors.
