Radium and Its Physical Properties. 341. Fig. 4. The three types of rays emitted by radium. Of the total radiation, alpharays represent 90 per cent. ; beta rays, 9 per cent. ; and gamma rays, 1 per cent. penetration is extreme, passing undisturbed through manycentimeters of lead. Of the total radiation of radium, alpharays represent 90 per cent.; beta rays, 9 per cent.; and gammarays, 1 per cent. ATOMIC DISINTEGRATION. Through Prof. Rutherfords work it became evident thatradio-activity is accompanied by manifestation of atomic dis-integration. It is known that in the smallest conceivable grainof matter there is a mentally inconceivable myriad of separateatoms. In a tiny quantity of radium bromide, weighing one-half of a grain, and assuming that the compound is pure, weknow with fair certainty that there are fifty million billionseparate atoms of radium (5X1019). It has been proven thatone-two-thousandth of these disintegrate yearly. There areabout 32,000,000 seconds in a year, so that every second of 342 The Hahncmannian Mon
