Re: Children in Research Areas

[steve hand <hand@wam.umd.edu>]

    In my copy under Question 26a  and the heading OCCUPATIONAL DOSE VS. PUBLIC
DOSE it says: By definition, and with the exceptions given in the definitions
of "occupational dose", any dose received by any individual in a "restricted
area" is an "occupational dose".  No one in a "restricted area" is a "member
of  the public."

Since no one is a restricted area is a member of the general public and doses
to members of the general public are not occupational doses by definition in
20.1003 then the doses to minors in a restricted area are limited to 10% of the
occupational limits 20.1207.

This would apply for example to grade school kids or high school kids who come
and take tours of the training reactor at our university and enter the
restricted areas.
