DHS 157.26(1)(c)(c) A licensee or registrant may apply to the department for approval of alternative methods for controlling access to high radiation areas. DHS 157.26(1)(d)(d) A licensee or registrant shall establish the controls required under par. (a) 1. and 3. in a way that does not prevent individuals from leaving a high radiation area. DHS 157.26(1)(e)(e) A licensee or registrant is not required to control each entrance or access point to a room or other area that is a high radiation area solely because of the presence of radioactive materials prepared for transport and packaged and labeled under the regulations of the U.S. department of transportation provided that all of the following conditions are met: DHS 157.26(1)(e)2.2. The dose rate at one meter from the external surface of any package does not exceed 0.1 mSv (10 mrem) per hour. DHS 157.26(1)(f)(f) A licensee or registrant is not required to control entrance or access to rooms or other areas in hospitals solely because of the presence of patients containing radioactive material, provided there are personnel in attendance who are taking the necessary precautions to prevent the exposure of individuals to radiation or radioactive material in excess of the established limits in this subchapter and to operate within the ALARA provisions of the licensee’s or registrant’s radiation protection program. DHS 157.26(1)(g)(g) A registrant is not required to control entrance or access to rooms or other areas containing sources of radiation capable of producing a high radiation area if the registrant has met all the specific requirements for access and control specified in other applicable parts of this chapter, such as subch. IV for industrial radiography and subch. VIII for x-rays in the healing arts and accelerators. DHS 157.26(2)(a)(a) In addition to the requirements in sub. (1), a licensee or registrant shall institute measures to ensure that an individual is not able to gain unauthorized or inadvertent access to areas in which radiation levels could be encountered at 5 Gy (500 rad) or more in one hour at one meter from a source of radiation or any surface through which the radiation penetrates. This requirement does not apply to rooms or areas in which diagnostic x-ray systems are the only source of radiation or to non-self-shielded irradiators. DHS 157.26(2)(b)(b) A licensee or registrant is not required to control entrance or access to rooms or other areas containing sources of radiation capable of producing a very high radiation area as described in par. (a) if the licensee or registrant has met all the specific requirements for access and control specified in other applicable parts of this chapter, such as subch. IV for industrial radiography and subch. VIII for x-rays in the healing arts and accelerators. DHS 157.26 HistoryHistory: CR 01-108: cr. Register July 2002 No. 559, eff. 8-1-02. DHS 157.27DHS 157.27 Respiratory protection and controls to restrict internal exposure in restricted areas. DHS 157.27(1)(1) Use of process or other engineering controls. A licensee or registrant shall use, to the extent practical, process or other engineering controls, such as containment, decontamination or ventilation, to control the concentrations of radioactive material in air. DHS 157.27(2)(a)(a) When it is not practical to apply process or other engineering controls to control the concentrations of radioactive material in air to values below those that define an airborne radioactivity area, a licensee or registrant shall increase monitoring and limit intakes by one or more of the following means: DHS 157.27(2)(b)(b) If a licensee or registrant performs an ALARA analysis to determine whether or not respirators should be used, a licensee or registrant may also consider the impact of respirator use on workers’ industrial health and safety. DHS 157.27(3)(3) Use of individual respiratory protection equipment. DHS 157.27(3)(a)(a) If a licensee or registrant uses respiratory protection equipment to limit intakes under sub. (2), all of the following criteria shall apply: DHS 157.27(3)(a)1.1. Except as provided in subd. 2., a licensee or registrant shall use only respiratory protection equipment that is tested and certified by the U.S. national institute for occupational safety and health. DHS 157.27(3)(a)2.2. A licensee or registrant may use equipment that has not been tested or certified by the U.S. national institute for occupational safety or for which there is no schedule for testing or certification, provided the licensee or registrant has submitted to the department and the department has approved a request for authorized use of that equipment. The request shall include documentation of a demonstration by testing, or a demonstration on the basis of test information, that the material and performance characteristics of the equipment are capable of providing the proposed degree of protection under anticipated conditions of use. DHS 157.27(3)(a)3.3. A licensee or registrant shall implement and maintain a respiratory protection program that includes all of the following: DHS 157.27(3)(a)3.a.a. Air sampling sufficient to identify the potential hazard, permit proper equipment selection and estimate doses. DHS 157.27(3)(a)4.4. A licensee or registrant shall have written procedures regarding all of the following:
