Gamma ray detection using our germanium semiconductor detector. The natural gamma background in the room. Simple exposure and counting of neutron activated samples. Neutron activation introduction . The saturation factor.
Maximum activity limits.
Intermediate experiments Either Neutron activation analysis of simple unknowns, and a cadmium ratio using interesting mineral samples, or Airborne radioactivity and gamma counting of particulate air samples. The hot hair laboratory . We will ship to Pullman, Washington 0.3 gram hair samples for irradiation. Upon return we will count them for longer half life components. The hot thyroid laboratory .
