Curium-248 standard neutron source
A new standard neutron source based on curium-248 has been developed, prepared, and certified. The curium-248 isotope is more long-lived than californium-252. The active core of this source is a pellet made of an alloy of platinum with curium. The measured full neutron yield for this source is 2.30 x 10(4) s(-1) with 4% error at 0.95 confidence.
