Title: Beta Spectroscopy
Post by: MrNrge on Sep 12, 2013, 12:13

Is there a product that will analize a beta spectrum that is not liquid scintillation?
Bench top portable would be nice also

That's a beta detector, not a spectrum analyzer.  There is a reason you have heard of Gamma Spec, and Alpha Spec, and not Beta Spec.  Beta decay is variable, with a maximum and an average energy.  Where Gamma's decay at the same energy every time.  So, you can't Identify the nuclide that decayed by beta.

You can hook up a beta detector to an instrument that tells you what energy it is detected at, but it would be mostly useless.

A tray of shields to determine end point energy and the half life is the Fred Flintstone methodology the analyzer was an ELT 1.0.

Sometimes known as a Calibrated Absorber Set.

Google search came up with this

Don't know a thing about it or if it works but it fits a benchtop

yes, I believe that we called it the feather analysis when I was in  the Navy.

An extrapolation chamber would probably be the most appropriate instrument for this application. Good luck.
