Publisher Summary This chapter focuses on radioactivity, which is the spontaneous disintegration (decay) of the nucleus with the emission of a particle. The rate at which a radioactive substance disintegrates (and thus the rate of release of particles) depends on the isotopic species, but there is a definite “decay law” that governs the process.

Radioactive Fallout and Radioactive Strontium
Science, 1956The contribution to environmental radioactivity of radioactivity due to fallout following the explosion of nuclear weapons is reviewed. Mechanisms by which /sup 90/Sr might be expected to enter the human body are discussed in detail. Data from nuclear weapons tests form the basis for the conclusion that the main part of the radioactivity from high ...

Radioactivity and Radioactive Substances
Physics Bulletin, 19544th edition. By Sir James Chadwick, D.Sc., LL.D., F.R.S. Revised and supplemented by Prof. J. Rotblat, M.A., D.Sc, F.Inst.P. (London : Sir Isaac Pitman & Sons Ltd.). Pp. 120. Price 12s. 6d. It is of interest to note how much of the material which appeared in the first edition of this book has earned its place in the present edition.

Journal of Occupational and Environmental Medicine, 1959
There is little doubt that atomic energy will assume an important role in our civilization, and it is appropriate that future possible hazards should be evaluated. At the present time, it can be concluded that there is no reason for any change in our nutritional habits or food technology as a result of fall-out contamination.

Radioactive substances have the ability to ionise the air surrounding them and it is this property that is used to distinguish them from materials which are not radioactive.

Nature, 1946
SINCE the discovery of the radioactivity of samarium by Hevesy and Pahl in 19321, several experimenters have examined the emitted radiations in detail2. It is well established that the main radiation consists of I±-particles of range 1.13 ± 0.02 cm., and the experiments of Wilkins and Dempster3 indicate that these particles are emitted by the isotope ...
