For the conditions and qualifications of this table, see Report
Nos. 1 and 2 of the Federal Radiation Council (FRC).
The
responsibility for establishing generally applicable environmental
standards was assigned to the Environmental Protection Agency
in 1970, but the guides here are still generally known as FRC
Radiation Protection Guides. The philosophy represented by these
guides is that the dose given in the table should not be exceeded
without careful consideration of the reasons for doing so, and that
every effort should be made to encourage the maintenance of
radiation doses as far below this guide as is practicable.
