Hi Radsafers – I’m looking for help on identifying an old source that
we recently came across here. The source is labeled: National Resource Alphatron Gauge The gauge was most likely manufactured around 1968 –
1969 and contains 500 uCI (microcuries)
of Ra-226. The source is cylindrical in shape about 7 in long and 2.5
inches in diameter. It was also labeled 0.05 rad –
8 hr at 1 ft. The source was most likely made in the late sixties, possibly
between 1968 and 1969 That is a new marking to me. I’m assuming that it
means the dose to an individual at 1 ft for 8 hrs in 0.05 rad.
If anyone has any information about this device I would vary
much appreciate hearing form you. Thanks in advance – Ken Ken Smith, CHP Radiation Safety Officer Environmental Health and Safety (EH&S) voice: (831) 459-3911 |
