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. ...
