WHAT IS IONIZING RADIATION Ionizing radiation IR is highenergy radiation Exposure to high doses of IR may cause adverse health e31ects Sources of IR exposure during military service include Proximity.

Applications. Artificially produced radioisotopes find many uses in agriculture, industry, medicine, forensic science, and scientific research.. The first practical application though of radioactivity was done by George de Hevesy in 1911. . Radiation Safety/Protection. Medical diagnostic x-rays contribute more to the exposure of the population than do all other man-made sources of radiation. As an occupational radiation worker, you may be exposed to more radiation that the general public.. Nazi Homayounnasab. Expert of radio monitoring. Scope. Mobile phone use all around the world has risen dramatically over the last 20 . years. P. eople . increasingly rely on mobile phones as their sole or primary means of telephone . Manuela .

Do you know that radiation is in the air we breathe, the food we eat, the water we drink? Ionizing radiation in particular is a double-edged sword that it is used to cure cancer but can also cause cancer: How could that be? . Radioactivity: The characteristic of various materials to emit ionizing radiation. Ionization: The removal of electrons from an atom. The essential characteristic of high energy radiations when interacting with matter.. Radiation Biology. Branch of biology concerned with the effects of ionizing radiation on living systems.
