So we sometimes write. The diagram shows the readings obtained when a Geiger Muller tube is placed near a piece of radioactive rock. Much shorter wavelengths bend or reflect very little and travel along the line of sight. Consider a carbon atom. There are, of course, limitations and inaccuracies to carbon dating. This means that alpha particles from ordinary alpha decay do not penetrate the outer layers of dead skin cells and cause no damage to the live tissues below. The nucleus consists of protons p and neutrons nand is extremely small. In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.
