 In its initial state after manufacture, the generator is capable of generating 10 watts of electricity, almost enough to power a compact fluorescent light bulb with light output equivalent to a 60-watt bulb.The generator contains the strontium-90 radioisotope, with a heating power of 250W and 1,480 TBq of radioactivity.Some Beta-M generators have been subject to incidents of vandalism when scavengers disassembled the units while searching for non-ferrous metals.
