These molecules are then subjected to bombardment by electrons, commonly from a Nickel-63
Under the proposed agreement, Ontario Power Generation expects to receive about 290 cubic feet of intermediate-level nuclear waste per year at the deep geologic repository, including carbon-14, with a half-life of about 5,000 years; nickel-59, with a half-life of 76,000 years; nickel-63
, with a half-life of 100 years; iodine-129, with a half life of 15.
The heart of the new battery is a dollop of nickel-63
, a radioactive isotope that emits high-speed electrons as it decays.
The prototype is made of a copper strip that is cantilevered above a thin film or radioactive nickel-63
, an isotope.
The device, which works only in a vacuum, gets power from nuclear decay within a film of radioactive nickel-63
Since April 1998, the firm has been marketing cobalt-60, iridium-192, strontium-89, barium-133, and nickel-63
