Twenty-six white male workers who did the original @entity16878 research and development work at Los Alamos have been examined periodically over the past 50 y to identify possible health effects from internal @entity16878 depositions. Their effective doses range from 0.1 to 7.2 Sv with a median value of 1.25 Sv. As of the end of 1994, 7 individuals have died compared with an expected 16 deaths based on mortality rates of U. @entity1762 males in the general population. The standardized mortality ratio (SMR) is 0.43. When compared with 876 unexposed Los Alamos workers of the same period, the @entity16878 worker's mortality rate was also not elevated (SMR = 0.77). The 19 living @entity1 have diseases and physical changes characteristic of a male population with a median age of 72 y (range = 69 to 86 y). Eight of the twenty-six workers have been diagnosed as having one or more @entity5 , which is within the expected range. The underlying cause of death in three of the seven deceased @entity1 was from @entity5 , namely @entity5 of prostate, lung, and bone. Mortality from all @entity5 was not statistically elevated. The effective doses from @entity16878 to these individuals are compared with current radiation protection guidelines.

Fifty years of @entity16878 exposure to the Manhattan Project XXXX workers: an update.
