Detecting and measuring ionizing radiation - a short history
www.iaea.orgIonizing radiation causes neutral atoms or molecules to acquire either a positive or negative electrical charge. The most commonly known types of ionizing radiation are alpha, beta, gamma, X, and neutron rays. Charged-particle radiation, such as alpha or beta rays, has a direct ionizing effect; whereas neutral radiation,

3. SUMMARY OF HEALTH EFFECTS OF IONIZING RADIATION
www.atsdr.cdc.govIonizing radiation is a form of radiation with sufficient energy to remove electrons from their atomic or molecular orbital shells in the tissues they penetrate (Borek 1993). These ionizations, received in sufficient quantities over a period of time, can result in tissue damage and disruption of cellular function
