WebGamma thermometers are similar to neutron thermopiles'-') but respond to gamma ray heating rather than heat from neutron induced reactions. The main advantages of gamma thermometersb) are that they are rugged, have long in-core life with constant sensitivity, and produce a low impedance electrical output signal without an external power supply.
