Strontium fluoride flowsheet development studies for the waste packaging program

Description: It was demonstrated that the modified version of the Martin flowsheet can produce SrF/sub 2/ of acceptable quality using a simulated feed of the same composition as the anticipated packaging plant feed. By careful control of operating conditions, strontium losses in the process can be reduced to an acceptable level. Using a nonrepresentative radioactive feed (which contained impurities not present in the simulated feed) high strontium losses were encountered in the feed purification step, altho… more

Biological effects of daily inhalation of radon and its short-lived daughters in experimental animals

Description: From symposium on noble gases; Las Vegas, Nevada, USA (24 Sep 1973). Exposures of rats, mice, and hamsters for 90 hours per week to radon daughters nanging from 2000 to 8500 WL, with and without 18 mu g per liter uranium ore dust, caused marked lifeshortening in all three species. Marked reduction in body weights occurred in all three species, with weight losses of 30 to 50% of control animal values in all species after 31/2 months of exposures. Mice exposed to radon daughters and ore dust were… more

Plutonium in surface soil in the Hanford plant environs

Description: Analyses for plutonium in air, water, and foodstuffs have long been part of the routine surveillance program at Hanford. In addition, the ground and other surfaces have been surveyed for plutonium where there was possible deposition from stack emissions, waste spills, etc., using direct instrument measurements. Detectable plutonium deposition from the few such incidents has been confined to restricted areas. The surface contamination level that can be detected with the portable instruments is a… more

Effects of intracavitary irradiation by californium-252

Description: From effects of neutron irradiation upon cell function conference; Munich, F. R. Germany (22 Oct 1973). Improvements in neutron dosimetry and additional information about the effects of neutrons caused renewed interest in fast neutrons for cancer therapy. The availability of encapsulated /sup 252/Cf has introduced the need for data on the response of normal tissues that are at risk during an intracavitary exposure to a /sup 252/Cf implant. The anatomical characteristics of the Hanford Miniature… more
