This document contains the report for the month of January 1946 for the Health Division and Biological Section of the Research Division at Clinton Laboratories. The complete original medical records of all Clinton Laboratories' personnel employed prior to 7/1/45 are being transferred to the University of Chicago files. A recommended health protection policy to be considered in plans for construction of the new heterogeneous pile has been set up. The absence of or small numbers of over-tolerance exposures to radiation and incidents involving activity hazards is the result of positive action on the part of personnel to prevent them. A thorough radiation survey was made of the Clinton Laboratories' cafeteria and equipment, and the only radioactive contamination found was a small amount of beta and gamma activity on the water dispenser and the outside door latches of the building. Readings made with a portable Scaler and Walkie-Talkie at a distance of 2-1/4 miles down wind from the pile were about four times as high as those taken up wind at the Medical Building inside the plant. Careful surveys are being made in the Plutonium Separations Building (204) while it is being renovated for use by chemists who will work with U-235. The general radiation background to the east and north of the Lanthanum Separations Building (706-D) was about 12 mr/hr during the past hot run due to airborne radioactive products from the cell ventilation duct on the east side of the building. The new instrument in Building 706-D for measuring continuously the beta and gamma airborne activity has been calibrated. The new system of having the Health-Physics chief surveyors deliver the overexposure reports to the Section Chiefs and to those responsible for the overexposure is an improvement over sending them out by plant mail. The loss of the SED men from the Health Physics section is presenting difficult problems of replacement and training. The chief effort of the Biological Section was directed toward closing out and writing up the biological program.
