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.

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.

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 ...

Publisher Summary This chapter describes radioactivity, also known as nuclear decay or radioactive decay. Radioactivity is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation, As each nucleus disintegrates, in its effort to find a more stable combination, it emits a charged particle that, because

IT is well known that the dust particles contained in moist air streaming with considerable velocity through a small hole towards a plane surface are deposited on it. This effect is currently used to determine the content of dust in the air by means of dust-counters.
