Abstract
Before discussing the properties of ionizing radiation in detail it is desirable to establish the basic principles of radiography. X-rays are generated in an X-ray tube when a beam of electrons is accelerated on to a target by a high voltage and stopped suddenly on striking the target. The X-rays produced have different wavelengths and different penetrating powers according to the accelerating voltage. Gamma-rays have the same physical nature as X-rays and are emitted by certain radioactive substances.
