The lung dissolution rates for PuO2 were determined using a 100 day in vitro experiment. A very small amount of the PuO2 rapidly dissolved with a half-time of approximately 10 days, while the majority of the material (>99%) dissolved with a half-time

No evidence has been found for the formation of particle-stable neutral nuclei with A ⩾ 6 in 400 GeV protonuranium interactions. The production probability limits are lower than published positive results from 24 GeV proton-tungsten interactions.

A search for particle-bound polyneutron systems (/sup 6/n-/sup 12/n) produced in approx. 700-MeV proton interactions with uranium has yielded negative results. A radiochemical technique was used. The limits on production cross section: 10/sup -3/ to
