These risks fall into three categories:-i. a cancer induction risk (mainly leukaemia) ii hereditary effects (as the fetus is a potential parent) iii. energy which travel in the form of wave, mechanical wave All rights reserved. Justification and optimization are the two fundamental principles of radiation protection in medical … Irrespective of how this advice is applied in practice, it is almost inevitable that a woman who has had an x-ray examination will subsequently discover that they are pregnant. Overview. In a particular group of TLDs, variation of the response of the dosimeters is the smallest one. Benefits from medical procedures greatly outweigh the potential small risk of harm from the amount of radiation used. However, exposure to the EMF with a frequency >100 kHz leads to effective absorbent energy and an increase in body temperature. The scientific and clinical foundations of Radiation Therapy are cross-disciplinary. more electric energy...it doesn’t get over here yet... suppose a risk of serious mental retardation (if the fetus is exposed in the critical 8-15 weeks period when the forebrain is being developed). Clinical (both "in-house" and "consulting") physicists typically deal with areas of testing, optimization, and quality assurance of diagnostic radiology physics areas such as radiographic X-rays, fluoroscopy, mammography, angiography, and computed tomography, as well as non-ionizing radiation … This book is intended as an assistant textbook in radiation physics and its applications in diagnostic radiological techniques in applied academic medical graduate programs.
