text: Also, the rare 250Cm isotope was synthesized in large quantities, which is very difficult to produce in nuclear reactors from its progenitor 249Cm – the half-life of 249Cm (64 minutes) is much too short for months-long reactor irradiations, but is very "long" on the explosion timescale.
text: The latter has a half-life of 351 years, which is relatively long when compared to the other isotopes produced in the reactor, and is therefore undesirable in the disposal products.
