Hi Andrey

Thank you very much indeed for your very informative reply and sorry for the delay in replying. I have been very busy.

It therefore sounds like it is a very bad idea so I won't persue it any further.

Kind regards

Tim

There is a large difference between the newer RID-6M and older RID-1/KI-1 (which Carl Willis examined) in terms of active material content. A 100-fold difference. Each of those devices contains 2 sources.
RID-6M should be 2x 5.7 uCi, while the older ones have 100x more: 2x 0.57 mCi.
Activity of the RID-6M (the majority coming from Am241 daughter) is quite low, ~0.5 uSv/h, so hardly measurable at some distance and with some shielding... That's all I'll say :D
