DHS 157.29(3)(a)(a) A licensee or registrant is not required to post caution signs in areas or rooms containing sources of radiation for periods of less than 8 hours if all of the following conditions are met: DHS 157.29(3)(a)1.1. The sources of radiation are constantly attended during these periods by an individual who takes the precautions necessary to prevent the exposure of individuals to sources of radiation in excess of the limits established in this subchapter. DHS 157.29(3)(a)2.2. The area or room is subject to the licensee’s or registrant’s control. DHS 157.29(3)(c)(c) Rooms or other areas in hospitals that are occupied by patients are not required to be posted with caution signs, provided that no member of the public could receive a deep dose equivalent in excess of 5 mSv (500 mrem) from entering the room during the patient’s stay. DHS 157.29(3)(d)(d) A room or area is not required to be posted with a caution sign because of the presence of a sealed source provided the radiation level at 30 centimeters from the surface of the sealed source container or housing does not exceed 0.05 mSv (5 mrem) per hour. DHS 157.29(3)(e)(e) A room or area is not required to be posted with a caution sign because of the presence of radiation machines used solely for diagnosis in the healing arts. DHS 157.29(4)(a)(a) A licensee or registrant shall ensure that each container of licensed or registered material bears a durable, clearly visible label bearing the radiation symbol and the words “CAUTION, RADIOACTIVE MATERIAL” or “DANGER, RADIOACTIVE MATERIAL.” The label shall also provide information, such as the radionuclides present, an estimate of the quantity of radioactivity, the date for which the activity is estimated, radiation levels, kinds of materials and mass enrichment, to permit individuals handling or using the containers or working in the vicinity of the containers to take precautions to avoid or minimize exposures. DHS 157.29 NoteNote: Mass enrichment is a process used to increase the percentage of the isotope U-235 present in refined uranium. The amount of U-235 present is expressed in percent enrichment on the label.
DHS 157.29(4)(b)(b) A licensee or registrant shall, prior to removal or disposal of empty uncontaminated containers to unrestricted areas, remove or deface the radioactive material label or otherwise clearly indicate that the container no longer contains radioactive materials. DHS 157.29(4)(c)(c) A registrant shall ensure that each radiation machine is conspicuously labeled cautioning individuals that radiation is produced when it is energized. DHS 157.29(5)(5) Exemptions to labeling requirements. A licensee or registrant is not required to label any of the following: DHS 157.29(5)(c)(c) Containers attended by an individual who takes the precautions necessary to prevent the exposure of individuals in excess of the limits established by this subchapter. DHS 157.29(5)(d)(d) Containers in transport and packaged and labeled under the regulations of the U.S. department of transportation. DHS 157.29 NoteNote: Labeling of packages containing radioactive materials is required by the U.S. Department of Transportation if the amount and type of radioactive materials exceeds the limits for an excepted quantity or article as defined and limited by U.S. Department of Transportation regulations 49 CFR 173.403 (m) and (w) and 173.421 to 173.424. DHS 157.29(5)(e)(e) Containers that are accessible only to individuals authorized to handle or use them, or to work in the vicinity of the containers, if the contents are identified to these individuals by a readily available written record. The record shall be retained as long as the containers are in use for the purpose indicated on the record. DHS 157.29 NoteNote: Examples of the type of containers in par. (e) are containers in locations such as water-filled canals or storage vaults.
DHS 157.29(5)(f)(f) Installed manufacturing or process equipment, such as piping and tanks. DHS 157.29(6)(a)(a) A licensee or registrant who expects to receive a package containing quantities of radioactive material in excess of a type A quantity shall make arrangements to receive the package under either of the following conditions: DHS 157.29(6)(a)2.2. Upon notification of the arrival of the package at the carrier’s terminal and possession of the package is taken expeditiously. DHS 157.29(6)(b)1.1. Monitor the external surfaces of a labeled package for radioactive contamination unless the package contains only radioactive material in the form of gas or in special form as defined in subch. I. DHS 157.29(6)(b)2.2. Monitor the external surfaces of a labeled package for radiation levels unless the package contains quantities of radioactive material that are less than or equal to the type A quantity. DHS 157.29(6)(b)3.3. Monitor all packages known to contain radioactive material for radioactive contamination and radiation levels if there is evidence of degradation of package integrity, such as packages that are crushed, wet or damaged.
