RF Axel, SecondLife asked:
Do radioisotope Thermo-Electric Generators use a safer radioative material, like thorium?
Richard - Traditionally, it’s been plutonium-238 which has been used for powering radioisotope Thermo-Electric Generators. Thorium is not used for such systems.
I assume it all depends on energy density, and longevity of the device.
Radium with a half life of 1600 years might be useful for a long life unit but the output would be pretty poor syhprum, Tue, 14th Feb 2012
