PPT-L32-Radiation dosimetry& Physics of Diagnostic X-rays

Radiation dosimetry is the quantitative description of the effect of radiation on living tissue The absorbed dose of radiation is the energy delivered to the tissue per unit mass Used of Absorbed dose. - .

To familiarize the student with the most important types and properties of dosimeters used in radiotherapy. . Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . Bureau of Radiation Protection. Refresher Training for . X-Ray Equipment .
