- Authorization for Individuals to Use Radioactive Material
Prior to the use of radioactive material, all personnel must submit a completed A-3, Authorization to Use Radioactive Materials, form to the RSO. This form must be an original (i.e., no photocopies) and may be obtained from the RSO. The qualifications of each individual are evaluated by the RSO and/or the RRSC. Once this form is submitted, the individual may work with radioactive material under the direct supervision of an authorized user. An authorized user is an individual who has completed the required training provided by the RSO and is approved to work under a designated radionuclide use permit. Direct supervision means that the fully authorized user must be present in the lab when radioactive material is being handled by the authorized user applicant.
a. Applicants with previous training/experience
Full authorization will be granted if all of the following conditions are met:
- The applicant has sufficient training and/or experience, as determined by the RSO, in the safe handling of radioactive material.
- The procedures to be performed are within the applicant's knowledge and ability.
- The applicant agrees in writing, by signing the A-3 form, to follow all Federal, State, and University regulations regarding the use of radioactive material.
- The applicant attends the Radiation Safety Orientation.
- The applicant passes the Radiation Safety Test.
b. Applicants without adequate training:
In addition to attending the orientation, individuals without adequate radiation safety training/experience must attend the Radiation Safety Course and pass the Radiation Safety Test. After completing one part of the training (orientation or course), individuals may be allowed to work with radioactive material under the supervision of a fully authorized user (i.e., work must be periodically reviewed) until the complete training and test requirements are satisfied.
c. Temporary personnel (<six months)
Individuals who will be using radioactive material for less than six months (e.g., summer students) must attend the Radiation Safety Orientation but are not required to complete the Radiation Safety Test. These individuals must work under the direct supervision of an authorized user.
d. Graduate students on rotation
Graduate students who are on rotation for less than eight weeks through a department may be exempt from the training referred to above. However, they must:
- Receive specific training in regards to laboratory radiation safety from the Permit Holder or his/her designee (i.e. authorized user).
- Read this manual and direct any questions to an authorized user or Radiation Safety.
- View the Radiation Safety videotapes. These may be borrowed and copied from the Radiation Safety Office.
- Sign the Training Confirmation form. This form must be kept in the Radionuclide Inventory and Survey Book. The training form will be checked by the Radiation Safety Staff during their laboratory audits.
The following limits must be placed on graduate students.
- The student must not work under a particular permit for more than eight weeks.
- All radioactive work must be performed under the direct supervision of an authorized user. (An authorized user must be present in the lab at all times.)
- No iodinations may be performed by these students.
- No experiments exceeding the activities specified below are allowed:
H-3 10 mCi Cl-36 100 m Ci C-14 10 mCi Ca-45 1 mCi Na-22 100 m Ci Cr-51 10 mCi P-32 100 m Ci I-125 10 m Ci P-33 1 mCi I-131 10 m Ci S-35 1 mCi For other nuclides
contact RSO, (274-4797)
If any of these restrictions can not be enforced, the student must complete appropriate paperwork (i.e.A-3 form) and supplementary training to become a fully authorized user.
e. Irradiator users
All individuals who wish to use an irradiator must first complete and submit an A-3a, Authorization to Use Radioactive Materials (Irradiator), form. Once this form is reviewed by the RSO, the individual will be added to the appropriate irradiator Radionuclide Use Permit and may independently operate the irradiator.
- Responsibilities of Each Authorized User
Each person using radioactive material must do all of the following:
- Read, understand, and follow all the rules and regulations contained in this manual as well as any special conditions specified on the appropriate permit. Individuals must also read any information distributed by the RSO (e.g., refresher training handouts, the Radiation Safety Newsletter, etc.).
- Keep radiation exposure As Low As Reasonably Achievable (ALARA).
- Wear the appropriate personnel radiation monitoring device issued. Each user is responsible for having appropriate bioassay procedures performed as stipulated by the RSO.
- Ensure that all radioactive material is secured from unauthorized use/removal (e.g., by locking unoccupied laboratories).
- Notify the RSO of pregnancy (if the employee wishes to do so) by submitting an A-7, Notice of Pregnancy, form.
- Maintain good housekeeping practices in the laboratory.
- Comply with restrictions regarding eating, drinking, smoking, storing consumable items, or applying cosmetics in laboratories.
- Label all containers of radioactive material, contaminated items, and radioactive waste.
- Survey oneself and work area for contamination and, if necessary, decontaminate before leaving the laboratory.
- Report spills and/or accidents involving radioactive material immediately to the RSO and the PH.
- Become familiar with the procedures for maintaining inventory records and laboratory surveys and the location of the Radionuclide Inventory and Survey Book and this manual.
- Submit new paperwork when working under a new permit. In addition, an A-13, Employee Status Change, form should be submitted to remove an authorized user from a permit.
- Comply with any requirements established by the RSO in conjunction with RRSC recommendations and NRC regulations.
