Ch. DHS 157 Note Note: Chapter HSS 157 as it existed on July 31, 2002 was repealed and a new chapter HFS 157 was created effective August 1, 2002, except subchapters II, VI and VII will go into effect 30 days after signature by the Governor of an agreement transferring regulatory authority to the state. Chapter HFS 157 was renumbered chapter DHS 157 under s. 13.92 (4) (b) 1., Stats., and corrections made under s. 13.92 (4) (b) 7., Stats., Register January 2009 No. 637.

DHS 157.01(1) (1) This chapter is promulgated under the authority of ss. 254.31 to 254.45, Stats. to regulate the receipt, use, transfer, possession, ownership or acquisition of any source of radiation. The standards in this chapter generally conform to nationally accepted standards for protection against the harmful effects of ionizing radiation. The publications referenced in this chapter are available for inspection at the department, the secretary of state's office, the legislative reference bureau and at the respective federal agency or organization website.
DHS 157.01(2) (2) Subchapter I establishes the definitions used in this chapter, prohibitions and general regulatory requirements.

DHS 157.01(4) (4) Subchapter III establishes standards for protection against ionizing radiation resulting from activities conducted under a license or registration issued by the department. The requirements of subch. III are designed to control the receipt, possession, use, transfer and disposal of sources of radiation by any licensee or registrant so that the total dose to an individual, including doses resulting from all sources of radiation other than background radiation, does not exceed the standards for protection against radiation prescribed in subch. III. However, nothing in subch. III limits actions the department may take to protect health and safety in an emergency.
DHS 157.01(5) (5) Subchapter IV establishes radiation safety requirements for persons using sources of radiation in industrial radiography.

DHS 157.01(7) (7) Subchapter VI establishes requirements for the medical use of radioactive material. The requirements provide for the radiation safety of workers, the general public and human research subjects.
DHS 157.01(8) (8) Subchapter VII establishes radiation safety requirements for operating irradiators that use sealed sources containing radioactive material to irradiate objects or materials using gamma radiation.
DHS 157.01(9) (9) Subchapter VIII establishes requirements for the use of diagnostic or therapeutic x-ray equipment, including accelerators, by or under the supervision of an individual authorized and licensed by state statutes to engage in the healing arts or veterinary medicine; and to establish registration requirements for radiation machines.
DHS 157.01(10) (10) Subchapter IX establishes radiation safety requirements for the use of cabinet and analytical x-ray systems.
DHS 157.01(11) (11) Subchapter X establishes requirements for persons licensed or registered under this chapter to provide workers with notices, instructions and reports relating to activities under a license or registration.
DHS 157.01(12) (12) Subchapter XI establishes options available to facilities and individuals in connection with department inspections to determine compliance with the provisions of this chapter and radiological working conditions or other requirements specified in a license.
DHS 157.01(13) (13) Subchapter XII establishes classification and fiscal penalty criteria for violations of license conditions, emergency orders or the requirements of this chapter; and criteria for requesting and scheduling hearings to contest department assessments of forfeiture, licensing actions or emergency orders.
DHS 157.01(14) (14) Subchapter XIII establishes requirements for the packaging, preparation for shipment and transportation of radioactive material.
DHS 157.01(15) (15) Subchapter XIV establishes radioactivity requirements for community water systems.
