salted meclear weapon A nuclear weapon which is designed such that a significant partion of the radioactivity of the particulate debris produced by its detonation results from the neutron activation of selected isotopes, deliberately introduced into the weapon for this purpose, sample cave Shielded v-shaped apparatus for rolling sample collection Various methods of atomic cloud sample hot filter paper before inserting rolled papers into carrying cases (pigs). collection have been tried at one time or another; the most satisfactory results have been obtained either by the use of drone aircraft guided through the atomic cloud or by means of manned aircraft, The samples collected are of two types; snap samples in which a container is filled with essentially gaseous material, and particulate samples obtained by drawing the air and other gases through a filter, sampling mission The combination of specific tasks required sampling pig A thick-walled container, usually of lead, used to obtain and prepare for shipment the exact types of samples required by various Federal agencies, to ship or store radioactive mterials, The container protects the person handling the active material from radiation.
