Webb20 feb. 2024 · The ionization chamber is a type of gas-filled radiation detector that is widely used for the detection and measurement of certain types of ionizing radiation, such as x-rays, gamma rays, and beta particles. It is also known as an ion chamber. Webbsumptions made when deriving the basic formula. MATSUZAWA et coll. (1974) sug- gested that perhaps the C,-values published by ICRU (1972) for use in calibrating high energy electrons may be incorrect by as much as 3 per cent. The basis for this view was the assumption that the ionization chamber wall with build-up cap was
