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.
