Series Description: This series contains correspondence, health reports, and other documentation relating to occupational exposure from radioactive dust at the Mallinckrodt Chemical Works Weldon Spring Plant. Included are records which indicate maximum dust exposure levels as 50 micrograms per cubic foot and actual concentrations in micrograms per cubic meter. The health reports provide the sample numbers, dates, hours, and descriptions, with results expressed in disintegrations per minute and disintegrations per minute per cubic meter. They also provide maximum beta and gamma activity dose rates to lungs, skin, and bone, and the number of workers whose exposures exceeded those rates. The series also includes policies and procedures for monitoring and testing exhaust systems.
