Alpha, beta and gamma radiation, illustration. Illustration showing the penetrative power of different types of radiation from radioactive materials. Alpha radiation is positively charged helium nuclei, which cannot penetrate skin or paper. Beta radiation consists of electrons which can penetrate skin and paper, but not a 3 millimetre thickness of aluminium. Gamma radiation consists of very short wavelength electromagnetic waves, and can penetrate, to some degree, thick blocks of lead. | |
