Part 700: Signs and Notices Requirements
700.20 Required Notices
700.30 Required Signs
700.40 Required Labeling
700.50 Radiation Areas
700.60 Electron Capture Detectors
700.10 Introduction - Areas where radioactive material or radiation-producing equipment are used or stored must be identified and posted as required by the Nuclear Regulatory Commission regulations or Idaho Radiation Control Regulations. Such identification allows individuals and emergency response units to understand the hazards of an area before entering that area.
700.20 Required Notices - Each area authorized for radioactive material use shall be conspicuously posted with the Nuclear Regulatory Commission "Notice To Employees" (NRC Form 3) and the University of Idaho "Notice To Employees" signs. The radiation safety officer or designee shall be responsible for providing and posting these notices.
700.30 Required Signs - Each area where radioactive materials are authorized for use or storage shall be conspicuously marked with a sign containing the radiation symbol and the wording "Caution - Radioactive Materials". This sign shall be posted at the entrance to an area using or storing radioactive materials and at places within the area where radioactive materials are routinely used or stored (e.g., fume hoods, freezers, refrigerators, waste containers). The authorized user is responsible for identifying these areas. The radiation safety officer or designee will be responsible for providing signs to each user.
Any area in which radiation-producing equipment is located or are being used must be posted with the "Caution - Radiation" sign, and the notice "Caution - Radiation: This equipment produces radiation when energized" shall be attached next to the controls.
700.40 Required Labeling:
(A) Areas where radioactive materials are used, containers of stock material, waste containers, instruments, and other articles used with radioactive materials must be clearly labeled with the following information: the radiation symbol, and the words "CAUTION - RADIOACTIVE MATERIAL." Compliance with labeling requirements shall be the responsibility of the authorized user. The labeling must be visible at all times, and must not degrade under normal working conditions.
(B) In addition, each container exceeding the activity level listed in Part 900 must be labeled with the radioisotope, the activity and the date of activity, and the chemical composition of the material.
(C) Radioactive labels and/or markings must be removed or defaced from decontaminated packages, containers or other items before they can be released for unrestricted use.
700.50 Radiation Areas - Areas where an individual might receive a radiation dose of five or more millirems but less than one hundred millirems in any one hour shall be marked with a sign containing the radiation symbol and the wording "Caution - Radiation Area." The radiation safety officer or designee shall be responsible for providing and posting these signs.
700.60 Electron Capture Detectors:
(A) Each electron capture detector containing a radioactive source must have a label attached showing the identity and activity of the radioactive material, the date the activity of the radioisotope was determined, the radiation symbol, and the words "Caution - Radioactive Material".
(B) Each gas chromatograph containing an electron capture detector with a radioactive source shall be conspicuously marked on the outside of the gas chromatograph with the following:
"This equipment contains a radioactive source registered with the University of Idaho radiation safety officer. Notify the radiation safety officer before removing the source from this location or upon any custodial change."
