| Summary: | beta and gamma components of radioactive particles and gamma charged particle equilibrium. The Miller-Reece model was contaminations. Compliance with IO CFR 20. 1 01 requires depth of 0.007 cm. Skin exposure can arise from both the effect of electronic equilibrium, selected thicknesses of establishment must be assessed for shallow doses to prevent for assessing skin dose stemming from hot particle found to agree closely with the experimental data while the gamma component of dose increases dramatically when layers of Lantz- Lambert model overestimated dose at shallow depths. large in comparison to the range of beta particles. Once the of the beta particles, skin dose is due solely to gamma protective clothing are interposed between the hot particle protective clothing layer is thicker than the maximum range radiation can contribute significantly to skin doses. The radiation. Charged particle equilibrium is not established at radiochromic dye film and a 6OCo hot particle source and dose shallow depths. The degree of electronic equilibrium source and the skin, and in cases where the hot particle is that exposure to the skin be evaluated over a I CM2 area at a The Nuclear Regulatory Commission has set the basic criteria the overassessment of skin dose because conventional fluence- tissue equivalent material were interposed between to-dose conversion factors are not applicable. To assess the was measured as a function of depth. These measured values were then compared to models which are used to calculate |
