Didelių įtėkių hadronų apšvitų dozimetrijos kombinuoti metodai ir įranga /

Dosimetry in the routine sense is the measurement of the absorbed dose in biological tissues and matter delivered by ionizing radiation or particle beams. Dosimetry is widely applied in the field of medical physics where it is inevitable for assessment of the radiation dose received by personnel and patients. Then radiation dose refers to the amount of energy deposited in matter and biological effects of radiation. The dose measurement unit is the gray (Gy) which defines the unit radiation energy deposited per mass unit (J/kg). This kind of dosimetry is used extensively for radiation protection. As various radiation types lead to different biological effects for the same deposited energy, a corrective radiation weighting factors are applied to convert the absorbed dose measured in the unit gray, into the equivalent dose measured in the unit sievert (Sv). The dose equivalent is the product of the absorbed dose of ionizing radiation and the dimensionless quality factor, defined as a function of linear energy transfer. The sievert represents the equivalent biological effect of a joule of radiation energy in a kilogram of human tissue related to a gray using quality factor.
