The Importance of absorbed dose in medical applications

Radiation damage depends on energy absorption, and is approximately proportional to the absorbed energy density in the tissue. In external radiation consideration with a certain energy flux, the amount of absorbed dose in each point of the tissue depends on the type of radiation, the radiation energy, the depth of the place of receipt, and the main components of the absorber environment. The absorbed energy in tissue is important in radiotherapy. This issue is well known for ionizing radiation such as X and Gamma, and is implemented in therapeutic protocols. But less attention is paid to laser therapy. Due to the actual risks of laser use, dosimeters in laser therapy are very important, in addition to observing the permissible radiation limits, in terms of radiation protection, radiation dose is required to achieve the desired effect from the requirements of this laser application in medicine.
