RE: Article: How I set off the subway radiation meter
Bill, John, et al.
The most impressive portion of the news story, IMHO, is the fact that the
policeman knew the right question to ask and knew that the radiation level
wasn't a threat.
The thoughts expressed are mine, mine, all mine!

Bill,
If you look at Reg Guide 8.39, which gives guidance on release criteria for
patients. A patient may be released if they have received 760 mCi of Tc-99m
(Yes, the number is 760) The corresponding dose rate is 58 mrem/hr at one
meter. Instructions on precautions are required if the patient received
over 150 mCi of Tc-99m and is being released. Since most nuclear medicine
scans are around 5 to 25 mCi of Tc-99m, patients are never help for "decay."
As you say, and I agree with:
It's not about dose, it's about trust.
Let's look at the real problem, for a change.

Presently 10 CFR 35.75(b) requires written instructions to released nuc med
patients only if the expected dose is likely to exceed 0.1 rem. I assume
that this patient was under the regulatory threshold.
IMHO, this requirement should apply to ALL nuc med patients, due to the
situation described, here.
