Operational procedure for the handling of radioactive materials

  1. Purpose. The use of radioactive materials is necessary in certain areas of academic research and instruction. Because of the potential for harm, however, specific procedures and controls have been instituted according to the stipulations of the state of Ohio, department of health, United States nuclear regulatory commission and the license issued to the university by the state. These procedures are given in detail in the Kent state university safety manual which is distributed to all nuclear regulatory commission (NRC) licensees on campus, and are summarized in this rule.
  2. Radiation safety officer. The university has a radiation safety officer appointed to oversee the use of radioactive materials. Some of the officer's specific duties are:
    1. To ensure that only individuals authorized in the license or persons under their direct supervision use radioactive materials.
    2. To assure appropriate use of personnel monitoring equipment such as film badges by individuals handling radioactive materials.
    3. To receive and monitor all incoming packages or radioactive materials.
    4. To assure that radioactive materials not in use are secure against unauthorized removal.
    5. To assure regular inspection of all laboratories using and/or storing radioactive materials.
    6. To assure that required records such as inventories, personnel exposure records, wipe tests records, and leak test records are maintained in compliance with state regulations.
    7. To assure that the terms and conditions of the state license(s) are met.
    8. To assure that relevant information supplied to the state of Ohio is kept up to date.
  3. Institutional bioassay program. Guidelines published by the United States NRC stipulate that individuals who handle large quantities of tritium (H-3) labeled compounds and/or large quantities of I-125 or I-131 labeled compounds must be bioassayed.
    1. The Kent state university bioassay program is designed to:
      1. Assure that the investigator has not inhaled, absorbed, or ingested H-3, I-125, or I-131 during the handling of large quantities of these isotopes.
      2. Take appropriate clinical action if certain levels of these radioactive materials are detected, to assure the continued health of the individual.
    2. Bioassays are performed on an "as needed" basis, and are only required under certain circumstances. Kent state university's policy is to minimize as much as possible those situations requiring bioassay.
  4. Institutional survey program. Monitoring shall consist of both radiation level surveys and surface wipes.
    1. Radiation level surveys will be used to verify that the radiation levels in all areas accessible to personnel are such that person could not receive exposures exceeding the state mandated limits.
    2. Surface wipes must be taken in all areas where radioactive materials are used, except where they are only used as sealed sources.
    3. Records are to be kept on all survey results including negative ones by the university radiation safety officer.
    4. Wipe tests for sealed sources mandated by state regulations will be conducted at required intervals by authorized individuals and submitted for analysis to properly licensed companies.
  5. Procedures for ordering, receiving, and securing materials; inventories.
    1. All radioactive materials are to be ordered through the university radiation safety officer. The purchasing office is instructed not to process any order for radioactive materials without the approval of the radiation safety officer or his designee. The radiation safety officer must ensure that the requested materials and quantities are authorized by the license and that possession limits are not exceeded.
    2. The radiation safety officer will inspect all incoming packages, and monitor them for contamination.
    3. All radioactive materials must be stored in areas of controlled access, to prevent unauthorized removal and/or use of the material.
    4. The radiation safety officer will maintain inventory records of radioactive materials on campus, indicating their use and disposition. The inventory will be updated monthly.
  6. Institutional laboratory safety.
    1. Rules for handling radioisotopes and instructions for emergency procedures are included in the radiation safety manual.
    2. Areas where materials are being used and stored are to be marked in accordance with the federal and state regulations.
  7. Institutional training program.
    1. Students and technical staff who will use unsealed radioactive materials in their work must first pass a written examination approved by the radiation safety committee. The examination will test the individual's knowledge of the fundamentals of radiation physics, the effects of radiation on living systems, principles and practice of radiation safety, measurement of radioactivity, monitoring techniques, the mathematics and calculations basic to the use and measurement of radioactivity, and local, state, and federal regulations.
    2. Other personnel working in laboratories where unsealed radioactive materials are handled must be trained by the licensee who is their supervisor.
    3. Students and staff who work with sealed sources must be trained by the licensee who is their supervisor.
    4. Authorized users of radioactive materials are given an annual briefing to keep their knowledge or regulations, policies and procedures current. Annual briefings are given for authorized users of radioactive materials, to keep their knowledge of regulations, policies, and procedures current.
    5. Housekeeping and security personnel are given annual briefings on the university's rules and procedures applicable to radioactive material handling and, in particular, to possible consequences and necessary safeguards of which they should be aware. Briefings will be done through memos sent to appropriate supervisors for distribution.
  8. Institutional waste disposal program.
    1. Solid and organic liquid radioactive wastes are collected and periodically removed from campus by a licensed firm, contracted to provide this service.
    2. Aqueous liquid wastes may be flushed down the drain in quantities not exceeding the prescribed limits in section 20.303, 10 CFR part 20.
    3. Animal tissues and liquid scintillation fluids containing 0.05 UCI/GM or less of H-3 or C-14 may be disposed of as nonradioactive materials.
  9. Institutional survey instrument calibration procedures; film badges.
    1. Survey meters are to be periodically calibrated by qualified firms.
    2. Film badges are acquired from and processed by qualified firms.
