RHS 8-30 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 μm, micron, and for three classes (D,W,Y) of radioactive material, which refer to their retention (approximately days, weeks, or years) 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 class (D, W, or Y) given in the column headed “Class” applies only to the inhalation ALIs and DACs given in Table I, columns 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 systems. 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 102 or 600, and 6E+0 represents 6 x 100 or 6. Table I “Occupational Values” Note that the columns in Table I of this schedule captioned, “Oral Ingestion ALI,” “Inhalation,” “ALI,” and “DAC,” are applicable to occupational exposure to radioactive material. The ALIs in this schedule are the annual intakes of a given radionuclide by the reference man, which would result in either a committed effective dose equivalent (CEDE) of 0.05 Sv (5 rem), stochastic ALI, or 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 Rule 0400-20-05-.32. The non-stochastic ALIs were derived to avoid non- stochastic effects, such as prompt damage to tissue or reduction in organ function. A value of wT = 0.06 is applicable to each of the five 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 four separate organs. Note that the dose equivalents for an extremity, skin, and lens of the eye are not considered in computing the CEDE 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:
4. If the identity and concentration of each radionuclide in a mixture are known, the limiting values should be derived as follows: determine, for each radionuclide in the mixture, the ratio between the concentration present in the mixture and the concentration otherwise established in Schedule RHS 8–30 for the specific radionuclide when not in a mixture. The sum of such ratios for all of the radionuclides in the mixture may not exceed “1” (i.e., “unity”). Example: If radionuclides “A,” “B,” and “C” are present in concentrations CA, CB, and CC, and if the applicable DACs are DACA, DACB, and DACC, respectively, then the concentrations shall be limited so that the following relationship exists: CA CB CC < 1 + + DACA DACB DACC SCHEDULE RHS 8–31 QUANTITIES a OF LICENSED MATERIAL REQUIRING LABELING Radionuclide Quantity Radionuclide Quantity (µCi) *a (µCi) *a Hydrogen–3 1,000 Iron–52 100 Beryllium–7 1,000 Iron–55 100 Beryllium–10 1 Iron–59 10 Carbon–11 1,000 Iron–60 1 Carbon–14 1,000 Cobalt–55 100 Fluorine–18 1,000 Cobalt–56 10 Sodium–22 10 Cobalt–57 100 Sodium–24 100 Cobalt–58m 1,000 Magnesium–28 100 Cobalt–58 100 Aluminum–26 10 Cobalt–60m 1,000 Silicon–31 1,000 Cobalt–60 1 Silicon–32 1 Cobalt–61 1,000 Phosphorus–32 10 Cobalt–62m 100 Phosphorus–33 100 Nickel–56 100 Sulfur–35 100 Nickel–57 100 Chlorine–36 10 Nickel–59 100 Chlorine–38 1,000 Nickel–63 100 Chlorine–39 1,000 Nickel–65 1,000 Argon–39 1,000 Nickel–66 10 Argon–41 1,000 Copper–60 1,000 Potassium–40 100 Copper–61 1,000 Potassium–42 1,000 Copper–64 1,000 Potassium–43 1,000 Copper–67 1,000 Potassium–44 1,000 Zinc–62 100 Potassium–45 1,000 Zinc–63 1,000 Calcium–41 100 Zinc–65 10 Calcium–45 100 Zinc–69m 100 Calcium–47 100 Zinc–69 1,000 Scandium–43 1,000 Zinc–71m 1,000 Scandium–44m 100 Zinc–72 100 Scandium–44 100 Gallium–65 1,000 Scandium–46 10 Gallium–66 100 Scandium–47 100 Gallium–67 1,000 Scandium–48 100 Gallium–68 1,000 Scandium–49 1,000 Gallium–70 1,000 Titanium–44 1 Gallium–72 100 Titanium–45 1,000 Gallium–73 1,000 Vanadium–47 1,000 Germanium–66 1,000 Vanadium–48 100 Germanium–67 1,000 Vanadium–49 1,000 Germanium–68 10 Chromium–48 1,000 Germanium–69 1,000 Chromium–49 1,000 Germanium–71 1,000 Chromium–51 1,000 Germanium–75 1,000 Manganese–51 1,000 Germanium–77 1,000 Manganese–52m 1,000 Germanium–78 1,000 Manganese–52 100 Arsenic–69 1,000 Manganese–53 1,000 Arsenic–70 1,000 Manganese–54 100 Arsenic–71 100 Manganese–56 1,000 Arsenic–72 100 Arsenic–73 100 *a To convert µCi to KBq, multiply the µCi value by 37.

of Schedule RHS 8–30 of this chapter, rounding to the nearest factor of 10, and arbitrarily constraining the values listed between 0.001 and 1,000 µCi (37 Bq and 37 MBq). Values of 100 µCi (3.7 MBq) have been assigned for radionuclides having a radioactive half–life in excess of 109 years, except rhenium, 1,000 µCi (37 MBq), to take into account their low specific activity. NOTE: For purposes of Rules 0400-20-02-.111, 0400-20-05-.114, and 0400-20-05-.140, where there is involved a combination of radionuclides in known amounts, the limit for the combination shall be derived as follows: determine, for each radionuclide in the combination, the ratio between the quantity present in the combination and the limit otherwise established for the specific radionuclide when not in combination. The sum of such ratios for all radionuclides in the combination may not exceed “1” –– that is, unity. *a To convert µCi to KBq, multiply the µCi value by 37.

They are applicable only to airborne radiological hazards and may not be appropriate to circumstances when chemical or other respiratory hazards exist instead of, or in addition to, radioactive hazards. Selection and use of respirators for such circumstances must also comply with U. S. Department of Labor regulations. Radioactive contaminants for which the concentration values in Table 1, Column 3 of schedule RHS 8–32 in this rule are based on internal dose due to inhalation may, in addition, present external exposure hazards at higher concentrations. Under these circumstances, limitations on occupancy may have to be governed by external dose limits. b Air purifying respirators with APF <100 shall be equipped with particulate filters that are at least 95 percent efficient. Air purifying respirators with APF = 100 shall be equipped with particulate filters that are at least 99 percent efficient. Air purifying respirators with APFs >100 shall be equipped with particulate filters that are at least 99.97 percent efficient. c The licensee may apply to the Division for the use of an APF greater than 1 for sorbent cartridges as protection against airborne radioactive gases and vapors (e.g., radioiodine). d Licensees may permit individuals to use this type of respirator who have not been medically screened or fit tested on the device provided that no credit be taken for their use in estimating intake or dose. It is also recognized that it is difficult to perform an effective positive or negative pressure pre-use user seal check on this type of device. All other respiratory protection program requirements listed in Rule 0400-20-05-.92 apply. An assigned protection factor has not been assigned for these devices. However, an APF equal to 10 may be used if the licensee can demonstrate a fit factor of at least 100 by use of a validated or evaluated, qualitative or quantitative fit test. e Under-chin type only. No distinction is made in this Schedule between elastomeric half-masks with replaceable cartridges and those designed with the filter medium as an integral part of the facepiece (e.g., disposable or reusable disposable). Both types are acceptable so long as the seal area of the latter contains some substantial type of seal-enhancing material such as rubber or plastic, the two or more suspension straps are adjustable, the filter medium is at least 95 percent efficient and all other requirements of this chapter are met. f The assigned protection factors for gases and vapors are not applicable to radioactive contaminants that present an absorption or submersion hazard. For tritium oxide vapor, approximately one-third of the intake occurs by absorption through the skin so that an overall protection factor of 3 is appropriate when atmosphere-supplying respirators are used to protect against tritium oxide. Exposure to radioactive noble gases is not considered a significant respiratory hazard, and protective actions for these contaminants should be based on external (submersion) dose considerations. g No NIOSH approval schedule is currently available for atmosphere supplying suits. This equipment may be used in an acceptable respiratory protection program as long as all the other minimum program requirements, with the exception of fit testing, are met (i.e., Rule 0400-20-05- .92). h The licensee should implement institutional controls to assure that these devices are not used in areas immediately dangerous to life or health (IDLH). i This type of respirator may be used as an emergency device in unknown concentrations for protection against inhalation hazards. External radiation hazards and other limitations to permitted exposure such as skin absorption shall be taken into account in these circumstances. This device may not be used by any individual who experiences perceptible outward leakage of breathing gas while wearing the device. SCHEDULE RHS 8-33 REQUIREMENTS FOR TRANSFER OF LOW-LEVEL RADIOACTIVE WASTE FOR DISPOSAL AT LAND DISPOSAL FACILITIES AND MANIFESTS
I. Manifest. A waste generator, collector, or processor who transports, or offers for transportation, low-level radioactive waste intended for ultimate disposal at a licensed low-level radioactive waste land disposal facility shall prepare a manifest. The manifest shall contain the information requested on applicable NRC Forms 540 (Uniform Low-Level Radioactive Waste Manifest (Shipping Paper)) and 541 (Uniform Low- Level Radioactive Waste Manifest (Container and Waste Description)) and, if necessary, on an applicable NRC Form 542 (Uniform Low-Level Radioactive Waste Manifest (Manifest Index and Regional Compact Tabulation)). NRC Forms 540 and 540A shall be completed and shall physically accompany the pertinent low-level waste shipment. Upon agreement between shipper and consignee, NRC Forms 541 and 541A and 542 and 542A may be completed, transmitted and stored in electronic media with the capability for producing legible, accurate and complete records of the respective forms. Licensees are not required to comply with the manifesting requirements of this rule when they ship:
8. “Generator” means a licensee operating under a license issued by the Division, the U.S. Nuclear Regulatory Commission, or another Agreement State who:
22. “Waste generator” means an entity, operating under a license issued by the Division, the U.S. NRC or another Agreement State, who:
24. “Waste type” means a waste within a disposal container having a unique physical description (i.e., a specific waste descriptor code or description; or a waste sorbed on or solidified in a specifically defined media). Information Requirements
A. General Information The shipper of the radioactive waste shall provide the following information on the uniform manifest:
3. The name, address and telephone number, or the name and U.S. EPA hazardous waste identification number for the carrier transporting the waste to the land disposal facility.
