A classic 1904 work, Nobel Laureate Ernest Rutherford describes his pioneering experiments with radioactivity. Includes a discussion of radioactive substances, examinations of the ionization theory of gases, methods of measurement, the nature of radiation, and the rate of emission of energy. Also includes properties of radiation, the continuous production of radioactive matter, radioactive emanations, more.The needle should be suspended either by a fine quartz fibre or a long bifilar suspension of silk. A very fine phosphor bronze wire of some length is also very satisfactory. A magnetic control is not very suitable, as it is disturbed by coils or dynamos working in the neighbourhood. ... It is convenient to use a condenser such that the potential of the needle does not fall more than a few per cent. per day.
