Question 220: 10 CFR 20.1602 gives requirements for
control for access to very high radiation areas, and has no
exemption clause. 10 CFR 20.1003 defines a very high
radiation area. (a) Are teletherapy rooms or fixed / field
radiography facilities, with beams that can deliver in
excess of 500 rad in 1 hour at 1 meter, very high radiation
areas? (b) Do the requirements in 20.1602 apply to
teletherapy rooms or fixed / field radiography facilities?
Answer: (a) Yes.
(b) Yes. However, this does not prohibit patients from
receiving prescribed medical treatment in a teletherapy
room (Reference: 10 CFR 20.1602, 10 CFR 20.1003)
