Re: Licensing and Use of Smoke Detectors



An IAEA document that helps to understand and to interpret exemption is the

Principles for the Exemption of Radiation Sources and Practices for

Regulatory Control, Safety Series 89, and IAEA, 1988

This specific source is Americium oxide (Chemical form), incorporated in

ceramic cylinder and poses no internal radiation hazard, and care should be

taken to avoid loss of containment or damage.

You limit your verbs to "acquire."  10 CFR 30.20 uses the verbs, "receives,

possesses, uses, transfers. owns, or acquires..."



Regarding your statement, "This regulation you cited does not in any way

tell

the recipient how they may or may not use the device once it is in their

hands.":  The key work is "device."  The source without the rest of the

smoke

detector is not a "device."  It is byproduce material subject to full NRC

licensing.



I agree that this is open to interpretation, but I'm cautious in such

situations, since I can't predict how a regulator will see it.



The opinions expressed are strictly mine.

It's not about dose, it's about trust.

Curies forever.
