Definition: | material that approximates to the composition and physical interaction of soft tissue in the human body, with respect to penetrating ionizing radiation, within specified limits, with a density of 1 g cm−3 and a mass composition of: - 76,2 % oxygène,
- 10,1 % hydrogène,
- 11,1 % carbone,
- 2,6 % azote
Note 1 to entry: Water can be considered as tissue-equivalent for all the penetrating ionizing radiations met in radioprotection. Note 2 to entry: This entry was numbered 393-14-78 in IEC 60050-393:2003.
