The RSO will review at least quarterly external radiation exposures of authorized users and workers to determine that their exposures are ALARA. Quarterly review of records of radiation level surveys. The RSO will review radiation levels in unrestricted and restricted areas to determine that they were at ALARA levels during the previous quarter.
1947 Oak Ridge National Laboratory poster. Health physics, also referred to as the science of radiation protection, is the profession devoted to protecting people and their environment from potential radiation hazards, while making it possible to enjoy the beneficial uses of radiation. Health physicists normally require a four-year bachelor’s ...
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". [1] Exposure can be from a source of radiation external to the human body or due to internal irradiation ...
0.01 Sv. The roentgen equivalent man (rem) [1][2] is a CGS unit of equivalent dose, effective dose, and committed dose, which are dose measures used to estimate potential health effects of low levels of ionizing radiation on the human body. Quantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation ...
Effective dose (radiation) Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1] It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is ...
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [1] As of 2007, "medical radiation exposure" was defined by the International Commission on Radiological Protection as ...
