RE: Neutron Survey Meter
Standard questions:Did you check your print-out for the possibility of summation peaks and escape peaks and correlate the energies to germane energies which fall off scale hi/lo? Beryllium seems unlikely. You probably already thought of all of this before so consider this as not being an affront to your process but rather my thinking 'out loud'.

Subject: Neutron Survey Meter
To All Radsafers
I read with interest earlier postings of similar requests for information:
We too have an old "Slow Neutron Survey Meter" made by Ekco Electronic Ltd
- Type N578M, which (as some of you will know) contains a radioactive
source. Our initial spectral investigations of the source indicate 2 peaks,
1 being identified as 241Am and the other remains unknown (possibly
Beryllium!).
The reason for our request is that we would like to dispose of the source,
but are unable to until we can identify the other unknown peak and
determine the source activity - there are no labels/markings either on the
meter itself or the source to indicate the nature of the radioactivity or
it's activity.
Any help whatsoever would be much appreciated.
Kind Regards
