The radiation dose is the total amount of radiation to which a person or an object is exposed. It can be measured and assessed in various ways, depending on the type of radiation involved and the application scenario.
The following are some of the common methods of measuring and assessing radiation dose.
1. Radiation dosimeter: A radiation dosimeter is an instrument used to carry out measurements of the dose of radiation acting on a system by means of specialized technology. It can enhance the measurement method for different corporate types of radiation, such as ionizing and non-ionizing radiation, and convert it into a readable digital or indicator display reading. Common radiation dosimeters include Geiger counters and ionization chamber radiation dosimeters.
2. Environmental Monitoring: Environmental monitoring is a method of assessing radiation dose by sampling and analyzing radiation in the environment. This method is often used to assess radiation levels over large areas, such as in the aftermath of a nuclear accident.
3. Biomonitoring: Biomonitoring is a method of assessing an individual's radiation exposure by detecting the radiation dose in the body. This method usually uses biological samples such as blood, urine or oral mucosa for analysis.
4. Personal Dosimeter: A personal dosimeter is a type of radiation dosimeter that relates an individual's radiation dose to time. This method is commonly used to assess the radiation dose of patients undergoing occupational or medical radiation therapy.
5. Computational modeling: Computational modeling is a method of assessing radiation dose through numerical calculations. This method is usually used to assess the radiation dose in complex situations such as nuclear power plant accidents.
It is important for us to note that different methods of measurement and assessment studies may yield different results for the enterprise, so when performing radiation dose assessment one should choose a method that is suitable for their particular application scenario and cross validate it by using multiple teaching methodology questions where possible.
