  skos:note "The sievert (stem:[\"unitsml(Sv)\"]) is a special name for joule per kilogram, and is the coherent SI unit for dose equivalent.\n\n[stem%unnumbered]\n++++\n1 \"unitsml(Sv)\" = 1 \"unitsml(J/kg)\"\n++++\n\nThe dose equivalent at a point in tissue is given by:\n\n[stem%unnumbered]\n++++\nH = int_0^(oo) Q(L)D_L \"d\"L\n++++\n\nwhere stem:[D_L = \"d\"D//\"d\"L] is the distribution of stem:[D] in stem:[L] at the point of interest. See <<icrp>>.\n\nThe quantities measured with radiation protection dosimeters are based on the definition stem:[H = Q D]. If various radiation qualities stem:[i] have to be simultaneously accounted for, the definition is:\n\n[stem%unnumbered]\n++++\nH = sum_i Q_i D_i.\n++++\n\nIn ICRU 51 this quantity is denoted as \"dose equivalent\".\n\nIn order to quantify the radiation exposition of the human body and to specify dose limits, use is made of a quantity defined in ICRP 103, the \"equivalent dose to a tissue or organ\": stem:[H_\"T\" = w_\"T\" sum_\"R\" w_\"R\" D_\"T,R\"]. The weighting factors stem:[w_\"T\"] for various tissues and organs stem:[\"T\"] and stem:[w_\"R\"] for various radiation qualities stem:[\"R\"] have been numerically laid down in ICRP 103. stem:[D_\"T,R\"] is the mean absorbed dose to tissue within a tissue or organ stem:[\"T\"], imparted by radiation with radiation quality stem:[\"R\"].\n"@en ;
