Question 85: In §20.1902, posting of areas is based upon
"dose equivalent." Is this "deep," "shallow," "lens of
eye," "total effective" or some combination of the above?
Answer: These posting requirements are based on the deep
dose equivalent for "radiation areas" and "high radiation
areas" and the absorbed dose at a tissue depth of 1 cm
(1000 mg/square cm) for "very high radiation areas." See
the answer to Question 74. (References: 10 CFR 20.1003,
10 CFR 20.1902)
