Most laboratory data on simulated nuclear weapon thermal pulses can be compared only indirectly with the results from field studies. To over-come this handicap, data of the type which could be obtained in field experiments were sought Burns from the following radiant exposure-simulated nuclear weapon pulse combinations were produced: (1) 5 cal/sq cm - 20 KT, ho KT, 100 KT, 1000 KT; (2) 10 cal/sq cm - 20 KT, 40 KT, 100 KT, 1000 KT, 10,000 KT; (3) 15 cal/sq cm - 100 KT, 1000 KT, 10,000 KT; and (4) 20 cal/sq cm - 100 KT, 1000 KT, 10,000 KT. With most of the combinations studied, a moderately wide range of burn severity occurred within the sixteen replications of a single exposure-pulse combination. Radiant exposures of 10 cal/sq cm resulted in nearly the same depth of damage with thermal pulses simulating 20 KT, 40 KT, 100 KT and 1000 KT weapons. Pulses simulating 100 KT, 1000 KT, and 10,000 KT weapons had little influence on burns produced by exposures of 15 cal/sq cm. With the 5 cal/sq cm exposure, maximum damage resulted from the use of a 20 KT pulse. On the other hand, less damage occurred from 20 cal/sq cm with the 100 KT pulse than with either 1000 KT or 10,000 KT pulses. Except for the 5 cal/sq cm exposure, the results are contrary to some earlier predictions of the effects of nuclear weapons.

In this report, an attempt is made to describe the characteristics and suggest the management in space of possible medical problems which might arise from hazards of space operations; attention will therefore not be given to possible naturally-occurring diseases. Writing is oriented to missions during which, due to the time required to return to Earth, the diagnosis and interim treatment of medical problems will have to be carried out in space. Therefore it is assumed in this report that diagnostic and treatment facilities will be available, and that advanced spacecraft concerned will provide a "shirtsleeve" environment in. which multidisciplined crews, including medically-trained personnel, will be able to live in - reasonable comfort.

This index is designed to cover the declassified and unclassified work of the University of Rochester Atomic Energy Project from its beginning in 1943 until July 1960. It contains titles of the work described in Manhattan District and Atomic Energy Commission reports as well as of material published in books and journals.
