Environmental consequences of postulated plutonium releases from Exxon Nuclear MOFP, Richland, Washington, as a result of severe natural phenomena

“…1975;EPA 1977;Martin and Bloom 1975;Healy 1977;U.S. Code 1976;Healy 1974;Guthrie and Nichols 1964;Hazle and Crist 1975;Kathren 1968;Dunster 1962). The EPA has proposed a guideline of 0.2 ~Ci/m2 for plutonium in the general environment (EPA 1977).…”

Radiological survey and decontamination of the former main technical area (TA-1) at Los Alamos, New Mexico

“…Neither recommendations for acceptable levels nor government standards for plutonium in soils were available. Individual recommendations for acceptable plutonium levels 18 " have been based primarily on considerations of surface contamination, whereas the majority of the plutonium contamination in the TA-1 area was subsurface. A study by Healy 18 considered the inhalation of surface plutonium as well as the ingestion of plutonium, either casually or deliberately.…”

“…Individual recommendations for acceptable plutonium levels 18 " have been based primarily on considerations of surface contamination, whereas the majority of the plutonium contamination in the TA-1 area was subsurface. A study by Healy 18 considered the inhalation of surface plutonium as well as the ingestion of plutonium, either casually or deliberately. The study recommended acceptable, subsurface plutonium levels of 500 dis/min/g (225 pCi/g) in any 1-cm-thick layer for particles smaller than 100-/um diameter or a total of 1000 dis/min/g (450 pCi/g) in all particle sizes.…”

“…Introduction In 1974In , 1975, and 1976 the Los Alamos Scientific Laboratory (LASL), at the instigation of and with the support of the Atomic Energy Commission (AEC) and later the Energy Research and Development Administration (ERDA), carried out surveys and decontamination operations on land in the townsite of Los Alamos, New Mexico, that had been the site of the main technical area of the Laboratory during the development of the atomic bomb and for some years thereafter. Later, the Laboratory facilities were relocated, leaving empty this desirable land near the center of town.…”

Environmental monitoring plan - environmental monitoring section. Revision 1

“…Healy (1974) states: "Plutonium is only slightly absorbed from the GI tract when ingested .... In rats, chronic ingestion at low mass concentrations of [plutonium] nitrate resulted in an average uptake of 0.0003% of that fed with 90% of the sma fraction which was absorbed deposited in the skeleton."…”
