One of my favorite activities is nuclear spectroscopy. This is the isotopic identification of radioactive elements through the measurement of their radiation’s energies. The nuclear spectroscopist can measure gamma rays, x-rays, alpha particles, and beta particles.

Through gifts, surplus and eBay purchases I have assembled two complete spectroscopy systems.  I am continuously experimenting with other systems, but these two are kept in tact and are well characterized, ready to count at a moments notice.

The first system is for measuring gamma rays in the energy range of 40 keV to 10 Mev:


The second system is for measuring alpha particles up to about 10 MeV:


I mention these systems as many of my blog posts will utilize these instruments.  It took years for me to develop this lab.  Let it be an inspiration that the dedicated & patient amateur can assemble similar systems.
