Re: Exploranium GR-130

["SBD" <sbd@co.dnet.mindef.nl>]

Inspectors of the Dutch Ministry of Environment use the Exploranium GR-130
during their picket service, when they are called in for
1. findings of radioactive material in scrap metal (several times a week)
2. accidents with (sometimes first unknown) radioactive material
to determine which nuclides they are dealing with.
Some weeks ago I saw its use for the first time. I was not impressed, as we
were dealing with instruments with radium paint and the GR-130 also
identified Co-60 peaks (which we found weird, and our measurements
afterwards proved us right). But this is only my personal experience of one
case of practical application of the GR-130. As a no-user, I can not give
you really valuable information on its usefullness in practice.

Right now we are in the process of determining whether the GR-130 is handy
for us too (we have a mobile laboratory in which we can do nuclide
specifications). We do use the GR-110 as one of our detectors, especially
for contamination screenings of buildings or areas before they get another
user or are being sold.
