Fla. Admin. Code Ann. R. 64E-5.1001 - Standards
(1) Radiation exposure to the public from
naturally occurring radioactive materials shall be maintained as low as
reasonably achievable. For the purposes of this part, the normal background
level of gamma radiation in buildings is 6 microroentgens (1.55 nC/kg) per hour
and the normal background radon decay product concentration in buildings is
0.004 Working Level (WL).
(2) The
mean gamma exposure rate in a building shall not exceed 20 microroentgens (5.16
nC/kg) per hour, including background, and the annual average radon decay
product concentration shall not exceed 0.02 WL, including
background.
