That eses the radioactive ofval that is transformed in
electric current. 1590 years is the life of one gram of
radium: that is half of the existing nucleus will
disintegrated and tne other half needs 1590 years more.
Using the principales of emission of radioactive energy and
that of absorption of energy by the photo-thermo-electric
panels, we suppose that we could achieve a
photo-thermo-*electric nuclear generator which would transform
radioactive energy into the electric current....
