Nuclear Radiation in Warfare
Leaving the bomb project
Working on the Manhattan Project at Los Alamos was a traumatic experience. It is not often given to one to participate in the birth of a new era. For some the effect has endured throughout theirExpand
The age factor in the susceptibility of man and animals to radiation. I. The age factor in radiation sensitivity in mice.
The effect of age on the sensitivity of man to ionizing radiations has for many years been recognised by radiotherapists who, on a somewhat empirical basis, have planned their treatment to take thisExpand
Variation of Sensitivity to Ionizing Radiation with Age
The variation of sensitivity with age is investigated, using as a criterion of radiation damage the LD50 at 30 days, in rats of different ages. Expand
Dose-response relationship in the yield of radiation-induced free radicals in amino acids.
The electron spin resonance technique has been used to study the production of long-lived radicals in glycine, alanine, valine, aspartic acid and glutamic acid and saturation was observed at high doses (in the megarad range). Expand
Tissue Dosage from Thorotrast in the Body
A quantitative study of the radiation dosage requires a technique employing microscopic analysis because it is known that thorotrast in the body forms aggregates of size similar to, or even greater than, the range of the α-particles, and in order to determine the energy dissipated in tissue this self-absorption has to be taken into account. Expand
Electron spin resonance studies of thermal effects in irradiated amino acids.
It was found that an exposure to doses greater than 50 megarads leads to a decrease in the number of radicals with increasing dose, and the shape of the signal was found to change. Expand
The scattering of alpha particles by helium
In order to obtain information about the levels of even spin and parity of 8Be at energies above 11 MeV, the differential cross-section for the α-particle-helium elastic scattering has been measuredExpand
The risks for radiation workers
The following topics are discussed: recommendations of the International Commission on Radiological Protection, methods for determining dose limits to workers, use of data from survivors of Hiroshima and Nagasaki for estimating risk factors, and evidence that risk factors for persons exposed to partial-body radiation and Japanese survivors are too low.
