Americium-242m

Americium-242m is a rare radioisotope produced only by Highly Enriched Plutonium-241 Fuel in RBMK nuclear reactors.

Production
Am242m makes up 35% of Pu241-based Short-Lived Nuclear Waste from RBMKs. It requires the SILEX to extract.

Uses
All forms of Americium fuel.

Trivia

 * Am242m is a metastable isomer that has a longer half-life than its normal state (of 16.02 hours), which is extremely rare.
