RE: Radsafers in the Denver area

["Strickert, Rick" <rstrickert@signaturescience.com>]

The old thorium-based lantern mantles work well for practice in

detecting gammas with standard GM survey meters.  They probably could be

used for beta detectors, too.



Newer lantern mantles use non-radioactive yttrium, so check the package

label.
