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
The DOE Ionizing Radiation Dose Ranges Chart - Energy
www.energy.govIonizing Radiation. Ionizing radiation is radiation that carries sufficient energy to release one or more electrons from their accustomed positions in atoms in matter through which it is traveling. Upon loss of one or more of its electrons, the atom is said to be ionized. The electrons and atoms may immediately recombine, and most do recombine,

www.who.intNon-Ionizing radiation (NIR) refers to radiative energy that, instead of producing charged ions when passing through matter, has sufficient energy only for excitation. Nevertheless it is known to cause biological effects. The NIR spectrum is divided into two main regions, optical radiations and electromagnetic fields. ...

TABLE OF CONTENTS
www.health.ny.gov(2) "Absorbed dose" means the energy imparted by ionizing radiation per unit mass of irradiated material. The units of absorbed dose are the gray (Gy) and the rad. (3) "Accelerator-produced material" means any material made radioactive by a particle accelerator.
Ionizing and Non-Ionizing Radiation Study Guide
www.aocopm.orgIonizing Radiation has sufficient energy to produce ions in matter at the molecular level. If that matter is a human significant damage can result including damage to DNA and denaturation of proteins. This is not to say that non-ionizing radiation can’t cause injury to humans but the injury is generally limited to
