WVU Hospital Purchasing Instructions
WVU Hospitals Purchasing Instructions
The immediate approval of a purchase order for radioactive material is delegated by the Nuclear Medicine Physician to the Nuclear Medicine Technologist. The Nuclear Medicine Physician must be authorized by the University Radiation Safety Committee to use radiopharmaceuticals for human use and such uses must be reviewed by the Radiation Safety Officer (RSO). The Nuclear Medicine Technologist is responsible for the inventory of all radioactive material used routinely. Radioactive materials will be procured from NRC or State licensed suppliers.
Ordering Radioactive Materials
A written directive will be obtained from the physician who will perform or oversee the procedure. The written directive will contain the isotope, total prescribed dose and signature and date of the authorized user.
Persons ordering the material will reference the physician's written request when placing the order. The physician’s request will indicate isotope, compound, activity level, patient’s name, etc.
The physician's written request will be referenced when receiving, opening, or storing the radioactive material.
It is essential that written records be maintained for all ordering and receipt procedures.
Use the above information to serve as a model for ordering radioactive material.
For deliveries during normal working hours, inform carriers to deliver radioactive packages directly to a specified area.
For deliveries during off-duty hours, inform security personnel or other designated persons if they should accept the delivery in accordance with Radiation Safety Precautions and provide designated persons with RSD contact information.
Receiving
Only Authorized Users or their designated representatives are allowed to open shipping containers that contain radioactive materials.
If no Authorized User, designee, or Radiation Safety Department (RSD) representative is available when a package arrives, it must be placed in a secure, pre-designated location within the facility. The package should remain sealed and unopened until an authorized individual is present.
All packages containing radioactive material must be inspected and surveyed as soon as possible after delivery:
During normal working hours: within 3 hours of receipt.
After normal working hours: within 3 hours of the start of the next working day.
Opening Shipping Containers
Put on gloves to prevent contamination. Always assume that the package and material inside are contaminated until proven otherwise.
Visually inspect the package for evidence of potential contamination (crushed, wet, damaged). If damage is noted, stop the procedure and notify the RSD or other knowledgeable person.
Measure the dose rate from the package at 1 meter and at the package surface. If it is higher than expected, stop and notify the RSD. The expected dose rate in mrem/hr at one meter should be close to the transportation index (T.I.) value as noted on the package [49 CFR 173.403]. The expected maximum dose rates at the surface of the package and Transportation Indices are listed below [49 CFR 172.403(c)]:
Label Type | Maximum Surface Reading (mrem/hr) | Transportation Index (mrem/hr) |
|---|---|---|
White I | 0.5 | 0 |
Yellow II | 0.5 – 50 | 0 < T.I. ≤ 1.0 |
Yellow III | 50 – 200 | 1.0 < T.I. |
The final delivery carrier and the NRC Operations Center (301-816-5100) or appropriate Agreement State Agency must be immediately notified by telephone [10 CFR 20.1906(d)] if external radiation levels exceed limits specified in 10 CFR 71.47.
Wipe at least 300 cm2 of the exterior of the package and analyze the wipe. The final delivery carrier and the NRC Operations Center (301-816-5100) or appropriate Agreement State Agency must be immediately notified by telephone [10 CFR 20.1906(d)] if removable surface contamination levels exceed the limits specified in 49 CFR 173.443.
Record the results of the external radiation (if applicable) and removable contamination surveys (if applicable).
Remove packing slip.
Open the outer package following the supplier’s instructions, if provided.
Open the inner package and verify that the contents agree with the packing slip.
Check the integrity of the final source container if not a gas or special form material. Look for broken seals or vials, loss of liquid, condensation, or discoloration of packing material. If anything unusual is found, stop and notify the RSD. Take appropriate precautions to prevent the spread of contamination. Notify the user of the material of any contamination found.
Check the user request to ensure that the material received is the material that was ordered.
Monitor the packing material and empty packages for contamination with a radiation detection survey instrument prior to discarding. If it is contaminated, treat it as radioactive waste.
Records
Each clinical area is responsible for maintaining the master record file or log of all radioactive material ordered, received, transferred, used and disposed. The Nuclear Medicine Technologist, Medical physicist or Dosimetrist will maintain these records under the supervision of the Radiation Safety Officer. Records of radiation surveys, incident reports, personnel dosimetry results, leak tests, and survey instrument calibration shall also be maintained in each clinical area.
The following records must be kept and are to be available for inspection at any time by the Radiation Safety Department and authorized regulatory agency representatives:
Type and amount of radionuclides on hand.
Results of radiation surveys.
Sealed source leak tests and inventories, dose calibrator quality control testing, and survey meter calibrations control testing, and survey meter calibrations.
Method and amount of disposal, including radiation survey results for material held for decay.
Patient dose records, including patient's name dose prescribed, dose assayed, type of procedure, and date. Records will be retained for review by the licensing body for the periods specified below.
The following records must be kept indefinitely:
Personnel Monitoring and Bioassay Records
Radiation Accident Investigation Results
Radiation Safety Committee Minutes
The following records must be kept for ten (10) years:
Medical Event Reports
The following records must be kept for five (5) years:
Sealed Source Leak Test and Inventory Results
The following records must be kept for three (3) years:
Patient Dose Records
Survey Results, Including Area Surveys and Hold For Decay Surveys
Mo-99 Breakthrough Results
Survey Meter Calibration and Dose Calibrator QC Test Results
