      Non-Ionizing Radiation • Non-ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules—that is, to completely remove an electron from an atom or molecule. PM 3 4. BASIC RADIATION PHYSICS 3 Physical quantities and units Physical quantities are characterized by their numerical value (magnitude) and associated unit. Symbols for physical quantities are set in italic type, while symbols for units are set in roman type (e.g. m = 21 kg; E = 15 MeV). The numerical value and the unit of a physical quantity must be separatedFile Size: KB.

Cutaneous radiation injury (CRI) occurs when a high radiation dose of rad (2 Gy) or higher causes injury to the skin. 8 Symptoms of CRI can appear within a few hours or several days or weeks after exposure and may include itchiness, tingling, abnormal skin redness (erythema), and swelling caused by a buildup of fluid (edema). Depending on the radiation dose, symptoms of .

This handbook for teachers and students was formulated based on the recommendations of a Consultants Meeting on International Syllabus for Radiobiology Teaching held December in Vienna, Austria. Radiation is energy in the form of waves of particles. There are two forms of radiation – non-ionizing and ionizing – which will be discussed in sections andrespectively.

ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.

Ionizing radiation, flow of energy in the form of atomic and subatomic particles or electromagnetic waves that is capable of freeing electrons from an atom, causing the atom to become charged (or ionized).Ionizing radiation includes the more energetic end of the electromagnetic spectrum (X-rays and gamma rays) and subatomic particles, such as electrons, neutrons, and alpha.

Non-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.

Ionizing radiation is a form of energy that acts by removing electrons from atoms and molecules of materials that include air, water, and living tissue.

The lOth Taylor lecture is the first to deal with nonionizing radiations and may be, therefore, of particular interest to the bioen- gineer. During early history biophysics and bioengineering were primarily concerned with ionizing radiation bioeffects and electrophysiology.Phytosanitary irradiation is a treatment that uses ionizing radiation on commodities, such as fruits and vegetables to inactivate pests, such as insects.

This method is used for international food trade as a means to prevent spread of non-native organisms. It is used as an alternative to conventional techniques, which includes heat treatment, cold treatment, pesticide sprays, high .
