SECRET, Special Report (vu) This report consists of eight separate papers prepared by Radiological Division for presentation at Ottawa, Canada, September 1955. The reports are as follows: 1. Protection of Eyes and Face Against Thermal Radiation. 2. Detection of Radioactive Contaminants in Potable Waters. 3. Potential of Industrial Smokes as Shields Against Thermal Radiation.

WP-1119, Operation TEAPOT. Michael J. Schumchyk and Edwin H. Bouton, 17 November 1955. CONFIDENTIAL-FORMERLY RESTRICTED DATA, Special Report round and aerial radiation-intensity measurements made by this project have been used to arrive at contour lines which close the 100 mr/hr at H + 1 hr dose-rate line and nearly close the 10 mr/hr at H +1 hr contour. These contours show that the area inside the 3,000 r/hr at j i
