(2)
The sum of the deep dose equivalent from external sources and the committed dose equivalent to
any individual organ or tissue, other than the lens of the eye, of 50 rems (500 mSv).
b. The annual limits to the lens of the eye, to the skin, and to the extremities, which are –
(1)
An eye-lens dose equivalent of 15 rems (150 mSv); and
(2)
A shallow-dose equivalent to the skin or to any extremity of 50 rems (500 mSv).
6.9.9.2.2
Dose Limit for Minors.
The annual occupational dose limits for minors (less than 18 years of age) are 10 percent of the annual occupational
dose limits specified for adults.
6.9.9.2.3
Embryo/Fetus Dose Limits.
6.9.9.2.4
Air Force:
The radiation dose to the embryo/fetus of an occupationally exposed pregnant female shall not exceed 0.5 rem (5 mSv)
for the entire pregnancy. Additionally, efforts should be made to maintain the exposures ALARA and relatively
uniform that is, free of substantial dose rate variations above monthly exposure rates. See AFI 48-125 for details.
6.9.9.2.5
Army:
The radiation dose to the embryo/fetus of and occupationally exposed pregnant female shall not exceed 0.5 rem (5 mSv)
for the entire pregnancy. Additionally, efforts should be made to maintain the exposures ALARA and relatively
uniform that is, free of substantial dose rate variations above monthly exposure rates. (Note: A formal declaration of
pregnancy is the prerogative of each pregnant female. A female occupationally-exposed to radiation does not fall under
the lower dose limit until she formally declares her pregnancy in a written statement, "I hereby make notification that I
am occupationally exposed to radiation in the course of my normal job duties, and that I am now pregnant. My
estimated date of conception is _______. I understand that by declaring my pregnancy, my occupational exposure to
ionizing radiation will be controlled as prescribed by DA Pam 40-18." The declaration shall be made on a SF 600
(Health Record--Chronological Record of Medical Care), signed and dated by the woman and placed in the woman's
health record. A copy shall also be provided to the RSO. (Note: If the dose to the embryo/fetus exceeds 0.5 rem (5
mSv) or is within 0.05 rems (0.5 mSv) of this dose at the time the woman declares the pregnancy to the RSO, the
organization shall be considered in compliance with the limit prescribed above provided that any additional dose to the
embryo/fetus does not exceed 0.05 rems (0.5 mSv) during the remainder of pregnancy.
6.9.9.3
Dose Limits for Individual Members of the Public.
The total effective dose equivalent to members of the public shall not exceed 100 mrem (1 mSv) in a year from all
radiation sources under control of the installation activity commander. Additionally, the dose in any unrestricted area
from external radiation sources such as industrial X-rays shall not exceed 2 mrem (20 microsieverts (mSv)) in any one
hour.
6.9.9.4
Multiple Sources of Radiation.
When any individual is likely to be exposed to radiation from more than one source simultaneously, or at different
times, the protection associated with each source shall be increased so that the total dose received by any one person
from all sources shall NOT exceed applicable exposure limits. Additionally, total effective dose equivalent (TEDE)
limits the sum of external and internal radiation exposure thus special consideration must be given to assure that the
combination of internal and external exposure does not exceed limits.
6.9.9.5
Medical, Dental and The Raputic Radiation, And Naturally Occurring Sources of Radiation.
Radiation exposures resulting from necessary medical and dental diagnostic or therapeutic X-ray procedures shall NOT
be included in the determination of the radiation exposure status of the individual concerned. Similarly, exposures
resulting from naturally occurring sources or from sources in consumer products, shall NOT be included in determining
