The Inverse-Square Law and the Exponential Attenuation Law Used to the Shielding Calculation in Radiotherapy on a High School Level
de Paiva, Eduardo
Physics Teacher, v54 n4 p239-242 Apr 2016
Every year millions of people contract cancer in the world, and according to prediction of the World Health Organization by the year 2030 there will be about 27 million new cases. Because of these figures and the resulting social and economic implications of this disease, radiotherapy, which is one form of treatment that uses ionizing radiation, has a great importance. In the classroom the teacher can introduce the subject of the use of ionizing radiation in medicine and the basic physical principles to calculate the thickness of the walls of the rooms that house ionizing radiation sources.
