Note 1: Many radionuclides transform into other radionuclides. In expressing the concentrations in Appendix A, the activity stated is that of the parent radionuclide and takes into account the radioactive decay products.
Note 2: For purposes of s. DHS 157.09 (2) where there is involved a combination of radionuclides, the limit for the combination should be derived as follows: Determine for each radionuclide in the product the ratio between the radioactivity concentration present in the product and the exempt radioactivity concentration established in Appendix A for the specific radionuclide when not in combination. The sum of such ratios may not exceed “1”.
Example:   Concentration of Radionuclide A in Product +
    Exempt concentration of Radionuclide A
    Concentration of Radionuclide B in Product <1
    Exempt concentration of Radionuclide B
Note 3: To convert µCi/ml to SI units of megabecquerels per liter multiply the above values by 37.
Example: Zirconium (40) Zr−97 (2x10−4 µCi/ml multiplied by 37 is equivalent to 74 x 10−4 MBq/l).

Chapter DHS 157
APPENDIX E
Annual Limits on Intake (ALI) and Derived Air Concentrations (DAC) of
Radionuclides for Occupational Exposure; Effluent Concentrations;
Concentrations for Release to Sanitary Sewerage
Introduction
For each radionuclide, Table I indicates the chemical form which is to be used for selecting the appropriate ALI or DAC value. The ALIs and DACs for inhalation are given for an aerosol with an activity median aerodynamic diameter (AMAD) of 1 (micron), and for the D, W and Y classes of radioactive material, which refer to their retention in the pulmonary region of the lung. This classification applies to a range of clearance half−times for D if less than 10 days, for W from 10 to 100 days, and for Y greater than 100 days. The D, W or Y class given in the column headed “Class” applies only to the inhalation ALIs and DACs given in Table I, column 2 and 3. Table II provides concentration limits for airborne and liquid effluents released to the general environment. Table III provides concentration limits for discharges to sanitary
sewerage.
Note: The values in Tables I, II, and III are presented in the computer “E” notation. In this notation a value of 6E−02 represents a value of 6 x 10−2 or 0.06, 6E+2 represents 6 x 1O2 or 600, and 6E+0 represents 6 x 100 or 6.
Table I “Occupational Values”
Note that the columns in Table I of this appendix captioned “Oral Ingestion ALI,” “Inhalation ALI” and “DAC” are applicable to occupational exposure to radioactive material. The ALIs in this appendix are the annual intakes of given radionuclide by “reference man” which would result in either (1) a committed effective dose equivalent of 0.05 Sv (5 rem), stochastic ALI, or (2) a committed dose equivalent of 0.5 Sv (50 rem) to an organ or tissue, non−stochastic ALI. The stochastic ALIs were derived to result in a risk, due to irradiation of organs and tissues, comparable to the risk associated with deep dose equivalent to the whole body of 0.05 Sv (5 rem). The derivation includes multiplying the committed dose equivalent to an organ or tissue by a weighting factor, wT. This weighting factor is the proportion of the risk of stochastic effects resulting from irradiation of the organ or tissue, T, to the total risk of stochastic effects when the whole body is irradiated uniformly. The values of wT are listed under the definition of weighting factor in s. DHS 157.03. The non−stochastic ALIs were derived to avoid non−stochastic effects, such as prompt damage to tissue or reduction in organ function.
Note: A description of the reference man is contained in the International Commission on Radiological Protection report, ICRP Publication 23, Reference Man: Anatomical Physiological and Metabolic Characteristics, Pergamon Press, Oxford (1975). The publication may be ordered from the web−site http://www.icrp.org/publications.asp.
A value of wT = 0.06 is applicable to each of the 5 organs or tissues in the “remainder” category receiving the highest dose equivalents, and the dose equivalents of all other remaining tissues may be disregarded. The following portions of the GI tract -stomach, small intestine, upper large intestine, and lower large intestine - are to be treated as 4 separate organs. Note that the dose equivalents for an extremity, skin and lens of the eye are not considered in computing the committed effective dose equivalent, but are subject to limits that must be met separately.
When an ALI is defined by the stochastic dose limit, this value alone is given. When an ALI is determined by the non−stochastic dose limit to an organ, the organ or tissue to which the limit applies is shown, and the ALI for the stochastic limit is shown in parentheses.
Abbreviated organ or tissue designations are used:
LLI wall = lower large intestine wall;
St wall = stomach wall;
Blad wall = bladder wall; and
Bone surf = bone surface.
The use of the ALIs listed first, the more limiting of the stochastic and non−stochastic ALIs, will ensure that non−stochastic effects are avoided and that the risk of stochastic effects is limited to an acceptably low value. If, in a particular situation involving a radionuclide for which the non−stochastic ALI is limiting, use of that non−stochastic ALI is considered unduly conservative, the licensee may use the stochastic ALI to determine the committed effective dose equivalent. However, the licensee shall also ensure that the 0.5 Sv (50 rem) dose equivalent limit for any organ or tissue is not exceeded by the sum of the external deep dose equivalent plus the internal committed dose equivalent to that organ, not the effective dose. For the case where there is no external dose contribution, this would be demonstrated if the sum of the fractions of the nonstochastic ALIs that contribute to the committed dose equivalent to the organ receiving the highest dose does not exceed unity, that is, intake of each radionuclide/ALIns =< 1.0. If there is an external deep dose equivalent contribution of Hd, then this sum must be less than 1 − (Hd/50), instead of =< 1.0.
