Abstract
I HAVE bombarded potassium chloride with the -rays of radium C of 55 mm. effective range and found that it acquires a greater radioactivity than that due to the natural activity of potassium. The effect is due to potassium, because no similar effect was exhibited by sodium chloride irradiated in the same conditions. In order to measure exactly the amount of induced radioactivity, all counting experiments were done by taking the difference between the number of impulses due to two identical samples of potassium chloride, one of which has been irradiated.
