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. 2-A-6 Note 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) 2-B-1 Appendix B of Subchapter 2 EXEMPT QUANTITIES (2/2/93) Radioactive Micro- Material curies

Only for shaven faces and where nothing interferes with the seal of tight-fitting facepieces against the skin. Hoods and suits are excepted. 3. The mode symbols are defined as follows: CF = continuous flow D = demand NP = negative pressure, that is, negative phase during inhalation PD = pressure demand, that is, always positive pressure PP = positive pressure RD = demand, recirculating or closed circuit RP = pressure demand, recirculating or closed circuit 4. a. The protection factor is a measure of the degree of protection afforded by a respirator, defined as the ratio of the concentration of airborne radioactive material outside the respiratory protective equipment to that inside the equipment, usually inside the facepiece, under conditions of use. It is applied to the ambient airborne concentration to estimate the concentrations inhaled by the wearer according to the following formula: Concentration inhaled = Ambient airborne concentration Protection factor b. The protection factors apply: (i) Only for individuals trained in using respirators and wearing properly fitted respirators that are used and maintained under supervision in a well- planned respiratory protective program. (ii) For air-purifying respirators only when high efficiency particulate filters, above 99.97% removal efficiency by thermally generated 0.3 Fm dioctyl phthalate (DOP) test or equivalent, are used in atmospheres not deficient in oxygen and not containing radioactive gas or vapor respiratory hazards. (iii)No adjustment is to be made for the use of sorbents against radioactive material in the form of gases or vapors. (iv) For atmosphere-supplying respirators only when supplied with adequate respirable air. Respirable air shall be provided of the quality and quantity required in accordance with the National Institute for Occupational Safety and Health and the Mine Safety and Health Administration certification described in 30 CFR 11. Oxygen and air shall not be used in the same apparatus. 4-A-3 5. Excluding radioactive contaminants that present an absorption or submersion hazard. For tritium oxide, approximately one-third of the intake occurs by absorption through the skin so that an overall protection factor of less than 2 is appropriate when atmosphere-supplying respirators are used to protect against tritium oxide. If the protection factor for respiratory protective equipment is 5, the effective protection factor for tritium is about 1.4; with protection factors of 10, the effective factor for tritium oxide is about 1.7; and with protection factors of 100 or more, the effective factor for tritium oxide is about 1.9. Air-purifying respirators are not suitable for protection against tritium oxide. See also footnote 9 concerning supplied-air suits. 6. Canisters and cartridges shall not be used beyond service- life limitations. 7. Under-chin type only. This type of respirator is not satisfactory for use where it might be possible, such as, if an accident or emergency were to occur, for the ambient airborne concentrations to reach instantaneous values greater than 10 times the pertinent values in Table I, Column 3 of Appendix B of Subchapter 4. This type of respirator is not suitable for protection against plutonium or other high-toxicity materials. The mask is to be tested for fit prior to use, each time it is donned. 8. a. Equipment shall be operated in a manner that ensures that proper air flow-rates are maintained. A protection factor of no more than 1000 may be utilized for tested-and-certified supplied-air hoods when a minimum air flow of 6 cubic feet per minute (0.17 m 3/min) is maintained and calibrated air line pressure gauges or flow measuring devices are used. A protection factor of up to 2000 may be used for tested and certified hoods only when the air flow is maintained at the manufacturer's recommended maximum rate for the equipment, this rate is greater than 6 cubic feet per minute (0.17 m 3/min) and calibrated air line pressure gauges or flow measuring devices are used. b. The design of the supplied-air hood or helmet, with a minimum flow of 6 cubic feet per minute (0.17 m 3/min) of air, may determine its overall efficiency and the protection it provides. For example, some hoods aspirate contaminated air into the breathing zone when the wearer works with hands-over-head. This aspiration may be overcome if a short cape-like extension to the hood is worn under a coat or over- alls. Other limitations specified by the approval agency shall be considered before using a hood in certain types of atmospheres. See footnote 9. 9. Appropriate protection factors shall be determined, taking into account the design of the suit and its permeability to the contaminant under conditions of use. There shall be a standby rescue person equipped with a respirator or other apparatus appropriate for the potential hazards and communications equipment whenever supplied-air suits are used. 4-A-4 10. No approval schedules are currently available for this equipment. Equipment is to be evaluated by testing or on the basis of reliable test information. 11. This type of respirator may provide greater protection and 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, must be taken into account in such circumstances. 12. Quantitative fit testing shall be performed on each individual, and no more than 0.02% leakage is allowed with this type of apparatus. Perceptible outward leakage of gas from this or any positive pressure self-contained breathing apparatus is unacceptable because service life will be reduced substantially. Special training in the use of this type of apparatus shall be provided to the wearer. Note 1: Protection factors for respirators approved by the U.S. Bureau of Mines and the National Institute for Occupational Safety and Health, according to applicable approvals for respirators for type and mode of use to protect against airborne radionuclides, may be used to the extent that they do not exceed the protection factors listed in this table. The protection factors listed in this table may not be appropriate to circumstances where chemical or other respiratory hazards exist in addition to radioactive hazards. The selection and use of respirators for such circumstances should take into account applicable approvals of the U.S. Bureau of Mines and the National Institute for Occupational Safety and Health. Note 2: Radioactive contaminants, for which the concentration values in Table I, Column 3 of Appendix B of Subchapter 4 are based on internal dose due to inhalation, may present external exposure hazards at higher concentrations. Under these circumstances, limitations on occupancy may have to be governed by external dose limits. 4-C-1 Appendix C of Subchapter 4 QUANTITIES 1 OF MATERIAL REQUIRING LABELING (2/2/93)

____________________________________________________________________________ Radionuclide Quantity Radionuclide Quantity (FCi)* (FCi)* NOTE: 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. 1The quantities listed above were derived by taking 1/10th of the most restrictive ALI listed in Table I, Columns 1 and 2, of Appendix B to Subchapter 4, rounding to the nearest factor of 10, and constraining the values listed between 37 Bq and 37 MBq (0.001 and 1,000 FCi). Values of 3.7 MBq (100 FCi) have been assigned for radionuclides having a radioactive half- life in excess of E+9 years, except rhenium, 37 MBq (1,000 FCi), to take into account their low specific activity. * To convert FCi to kBq, multiply the FCi value by 37. 4-D-1 Appendix D of Subchapter 4 RADIATION SYMBOL (8/19/98) Cross-hatched area is magenta, or purple, or black.
