Nuclear energy in sky and satellite blasting

Four country’s top class mission, blast satelite in sky. Maybe fuel tank is full with nuclear energy…
Ureniyom Alpha, beta, game Ray’s touch is harmful to body in presence of sun light and it is big bad process from relieving them.
India, China, USA, still not mention such focused things on same as satelite fuel is full with ureniyom or not
What India needs?
Jay Mataji/Vande mataram/Jay Hind
Cause if satelite fuel tank disclose the uranium iso tops while blasting in space, may be harmful to everyone & all four countries are not yet given report on alpha beta gama Ray’s, as how much percentage damage on earth by same….
I know the notes are yet half compile by myself, but similarly government also not showing exact future path of safe life…
We all know nuclear energy is very much harmful and recently after eight years Fukushima plants solution came….by report….if any thing done in sky related nuclear energy, who will respond on same????
BIG QUESTION isn’t so????

Few reference...

Radioisotope Thermoelectric Generators (RTGs) have been the main power source for US space work since 1961. The high decay heat of Plutonium-238 (0.56 W/g) enables its use as an electricity source in the RTGs of spacecraft, satellites and navigation beacons.

Voyager 1 has three radioisotope thermoelectric generators (RTGs) mounted on a boom. Each MHW-RTG contains 24 pressed plutonium-238 oxide spheres. The RTGs generated about 470 W of electric power at the time of launch, with the remainder being dissipated as waste heat.
