[ RadSafe ] SCBA and beta dose connection?

[Perle, Sandy]

Rob, yes, a facility can take credit for any shielding over the eye. We have clients that we provide for the correction based o9n their evaluation and input, or, the facility applies the factor after they receive their dose report and/or electronic file and make the adjustment on their system, using the data we provide. This is perfectly acceptable. Not different than a medical professional wearing a leaded apron. The dose assigned can come from an actual dosimeter reading or applied by the facility to the un-attenuated dose reported.

Regards,

Sandy

Dose to the lens of the eye is measured at 300 mg/cm^2, so if there is shielding, you may be able to account for its effect on lens of the eye dose, expecially if you have a study to back up your reasoning.  I don't know if Lens dose is limiting in your situation but if so, you may be able to extend your times by accounting for shielding.

I have a document in front of me that states, " IF SCBAs are used, the beta
dose rates may be neglected."  The context is in a post -accident mission
dose determination where the effect of SCBAs is discussed. I'll admit my
ignorance on this one.  Does anybody know where this came from or what would
support it?

thx in advance  - -jmr
