NRC Supplementary Information - Manual

The aerosol neutralizers listed above contain radioactive material in the form of Krypton-85 gas. In the United States the possession and use of radioactive materials falls under the regulatory authority of the U.S. Nuclear Regulatory Commission (NRC) at the federal level, or of a regulatory agency in your state. This depends on whether your state has entered into an agreement with the NRC for the purpose of controlling the use of radioactive material within the state. The states that appear on the list enclosed have their own control programs and are therefore called Agreement States. If your state is not on the list, your possession and use of the aerosol neutralizer is regulated by the NRC. The NRC divides itself into four regions across the United States (see Part 20, Appendix D enclosed).
