Sec. 835.1304  Nuclear accident dosimetry.

    (a) Installations possessing sufficient quantities of fissile 
material to potentially constitute a critical mass, such that the 
excessive exposure of individuals to radiation from a nuclear accident 
is possible, shall provide nuclear accident dosimetry for those 
individuals.
    (b) Nuclear accident dosimetry shall include the following:
    (1) A method to conduct initial screening of individuals involved in 
a nuclear accident to determine whether significant exposures to 
radiation occurred;
    (2) Methods and equipment for analysis of biological materials;
    (3) A system of fixed nuclear accident dosimeter units; and
    (4) Personal nuclear accident dosimeters.

Appendix A to Part 835--Derived Air Concentrations (DAC) for Controlling 
             Radiation Exposure to Workers at DOE Facilities

    The data presented in appendix A are to be used for controlling 
individual internal doses in accordance with Sec. 835.209, identifying 
the need for air monitoring in accordance with Sec. 835.403, and 
identifying the need for posting of airborne radioactivity areas in 
accordance with Sec. 835.603(d).
    The DAC values are given for individual radionuclides. For known 
mixtures of radionuclides, determine the sum of the ratio of the 
observed concentration of a particular radionuclide and its 
corresponding DAC for all radionuclides in the mixture. If this sum 
exceeds unity (1), then the DAC has been exceeded. For unknown 
radionuclides, the most restrictive DAC (lowest value) for those 
isotopes not known to be absent shall be used.
    The derived air concentrations (DAC) for limiting radiation 
exposures through inhalation of radionuclides by workers are listed in 
this appendix. The values are based on either a stochastic (committed 
effective dose equivalent) dose limit of 5 rems (0.05 Sv) or a non-
stochastic (organ) dose limit of 50 rems (0.5 Sv) per year, whichever is 
more limiting.

    Note: the 15 rems [0.15 Sv] dose limit for the lens of the eye does 
not appear as a critical organ dose limit.)

    The columns in this appendix contain the following information: (1) 
Radionuclide; (2) inhaled air DAC for lung retention class D, W, and Y 
in units of Ci/ml; (3) inhaled air DAC for lung retention class 
D, W, and Y in units of Bq/m 3; and (4) an indication of 
whether or not the DAC for each class is controlled by the stochastic 
(effective dose equivalent) or nonstochastic (tissue) dose. The classes 
D, W, and Y have been established to describe the clearance of inhaled 
radionuclides from the lung. This classification refers to the 
approximate length of retention in the pulmonary region. Thus, the range 
of half-times for retention in the pulmonary region is less than 10 days 
for class D (days), from 10 to 100 days for class W (weeks), and greater 
than 100 days for class Y (years). The DACs are listed by radionuclide, 
in order of increasing atomic mass, and are based on the assumption that 
the particle size distribution of the inhaled material is unknown and an 
assumed particle size distribution of 1 m is used. For 
situations where the particle size distribution is known to differ 
significantly from 1 m, appropriate corrections can be made to 
both the estimated dose to workers and the DACs.

Footnotes for Appendix A
\1\ A determination of whether the DACs are controlled by stochastic (St) or nonstochastic (organ) dose, or if they both give the same result (E), for
  each lung retention class, is given in this column. The key to the organ notation for nonstochastic dose is: BS= Bone surface, K= Kidney, L= Liver,
  SW= Stomach wall, and T= Thyroid. A blank indicates that no calculations were performed for the lung retention class shown.
\2\ The ICRP identifies tritiated water and carbon as having immediate uptake and distribution; therefore no solubility classes are designated. For the
  purposes of this table, the DAC values are shown as being constant, independent of solubility class. For tritiated water, the inhalation DAC values
  allow for an additional 50% absorption through the skin, as described in ICRP Publication No. 30: Limits for Intakes of Radionuclides by Workers. For
  elemental tritium, the DAC values are based solely on consideration of the dose-equivalent rate to the tissues of the lung from inhaled tritium gas
  contained within the lung, without absorption in the tissues.
\3\ A dash indicates no values given for this data category.
\4\ These values are appropriate for protection from radon combined with its short-lived daughters and are based on information given in ICRP
  Publication 32: Limits for Inhalation of Radon Daughters by Workers and Federal Guidance Report No. 11: Limiting Values of Radionuclide Intake and Air
  Concentrations, and Dose Conversion Factors for Inhalation, Submersion, and Ingestion (EPA 520/1-88-020). The values given are for 100% equilibrium
  concentration conditions of the radon daughters with the parent. To allow for an actual measured equilibrium concentration or a demonstrated
  equilibrium concentration, the values given in this table should be multiplied by the ratio (100%/actual %) or (100%/demonstrated %), respectively.
  Alternatively, the DAC values for Rn-220 and Rn-222 may be replaced by 1 WL* and 1/3 WL*, respectively, for appropriate limiting of daughter
  concentrations. Because of the dosimetric considerations for radon, no f1 or lung clearance values are listed.
*A ``Working Level'' (WL) is any combination of short-lived radon daughters, in one liter of air without regard to the degree of equilibrium, that will
  result in the ultimate emission of 1.3 E+05 MeV of alpha energy.

                   Appendix B to Part 835  [Reserved]

  Appendix C to Part 835--Derived Air Concentrations (DAC) for Workers 
 From External Exposure During Immersion in a Contaminated Atmospheric 
                                  Cloud

    a. The data presented in appendix C are to be used for controlling 
occupational exposures in accordance with Sec. 835.209, identifying the 
need for air monitoring in accordance with Sec. 835.403, and identifying 
the need for posting of airborne radioactivity areas in accordance with 
Sec. 835.603(d).
    b. The air immersion DAC values shown in this appendix are based on 
a stochastic dose limit of 5 rems (0.05 Sv) per year or a nonstochastic 
(organ) dose limit of 50 rems (0.5 Sv) per year. Four columns of 
information are presented: (1) Radionuclide; (2) half-life in units of 
seconds (s), minutes (min), hours (h), days (d), or years (yr); (3) air 
immersion DAC in units of Ci/ml; and (4) air immersion DAC in 
units of Bq/m3. The data are listed by radionuclide in order 
of increasing atomic mass. The air immersion DACs were calculated for a 
continuous, nonshielded exposure via immersion in a semi-infinite 
atmospheric cloud. The DACs listed in this appendix may be modified to 
allow for submersion in a cloud of finite dimensions.
    c. The DAC value for air immersion listed for a given radionuclide 
is determined either by a yearly limit on effective dose equivalent, 
which provides a limit on stochastic radiation effects, or by a limit on 
yearly dose equivalent to any organ, which provides a limit on 
nonstochastic radiation effects. For most of the radionuclides listed, 
the DAC value is determined by the yearly limit on effective dose 
equivalent. Thus, the few cases where the DAC value is determined by the 
yearly limit on shallow dose equivalent to the skin are indicated in the 
table by an appropriate footnote. Again, the DACs listed in this 
appendix account only for immersion in a semi-infinite cloud and do not 
account for inhalation or ingestion exposures.
    d. Three classes of radionuclides are included in the air immersion 
DACs as described below.
    (1) Class 1. The first class of radionuclides includes selected 
noble gases and short-lived activation products that occur in gaseous 
form. For these radionuclides, inhalation doses are negligible compared 
to the external dose from immersion in an atmospheric cloud.
    (2) Class 2. The second class of radionuclides includes those for 
which a DAC value for inhalation has been calculated, but for which the 
DAC value for external exposure to a contaminated atmospheric cloud is 
more restrictive (i.e., results in a lower DAC value). These 
radionuclides generally have half-lives of a few hours or less, or are 
eliminated from the body following inhalation sufficiently rapidly to 
limit the inhalation dose.
    (3) Class 3. The third class of radionuclides includes selected 
isotopes with relatively short half-lives. These radionuclides typically 
have half-lives that are less than 10 minutes, they do not occur as a 
decay product of a longer lived radionuclide, or they lack sufficient 
decay data to permit internal dose calculations. These radionuclides are 
also typified by a radioactive emission of highly intense, high-energy 
photons and rapid removal from the body following inhalation.
    e. The DAC values are given for individual radionuclides. For known 
mixtures of radionuclides, determine the sum of the ratio of the 
observed concentration of a particular radionuclide and its 
corresponding DAC for all radionuclides in the mixture. If this sum 
exceeds unity (1), then the DAC has been exceeded. For unknown 
radionuclides, the most restrictive DAC (lowest value) for those 
isotopes not known to be absent shall be used.
