  2. Instructor Dennis Widner Health Physicist – Training 542-0526

  3. Why do we have to take a course on Radiation Safety ? Since UGA possesses and uses RAMs, it is state law and a requirement of UGAs RAM license that training be provided and documented as part of a Radiation Protection Program and testing conducted to assure that you are trained! Annual requalification must be performed.

  4. Why do we have Radiation Safety at UGA? To instruct you how to protect yourself and others from ionizing radiation. What is Ionizing radiation and why is it dangerous? Use of RAM in research at UGA has been documented since 1965 and in conjunction with this research, a radiation safety program has co-existed for your protection.

  5. What is Radiation Safety? The science to limit health problems associated with the internal and external exposure to radiation or radioactive material to the individual and potential offspring, through precautions and procedures to minimize this exposure, and in the purposes and functions of protective devices employed.

  9. RESPONSIBILITY AND AUTHORITY OF THE RADIATION SAFETY COMMITTEE (RSC) • The Committee is appointed by the President of the University • The Committee will establish radiation safety policy The policy will be designed to: • Protect faculty, staff, students, visitors and the public from • hazardous radiological conditions • Keep the University in compliance with state and federal regulations and the conditions of the University’s license • Maintain all radiation exposure as low as reasonably achievable (ALARA)

  10. The Radiation Safety CommitteeThe University of Georgia Radiation Safety Committee is comprised of faculty, administrators and staff who have been delegated responsibility for radiological health, safety and compliance at the University. The RSC functions include; Review of radiation safety policy Review of campus radiation safety Advisement to the university administration about radiation safety issues and programs Ensures that audits of the operations and activities of the UGA Radiation Safety Office Approvals and permits for use of radioactive and ionizing materials at UGA Radiation Safety Disciplinary Hearings

  11. The Authorized User (AU) The RSC will authorize faculty members for the use of radioactive materials after submission of a written application if it is determined that safety requirements will be met. Faculty members and other individuals so authorized shall be referred to as “Authorized Users” The applicant must have adequate training and experience to safely handle the types and quantities of radioactive materials requested. The applicant must have adequate space, facilities, and equipment to safely use and possess the radioactive materials requested. The applicant must agree to comply with guidelines stipulated in the UGA Radiation Safety Manual and with any other written directives authorized by the RSC.

  12. Responsibilities of the Authorized User To ensure that the policies in the UGA/RSM are observed by all personnel under their direction To make available appropriate radiation safety procedures and policies to be observed in the permitted use location To see that radiological surveys are made and records kept as required by the Radiation Safety Officer and the UGA/RSM To keep an up-to-date inventory of radioactive materials under control of the Authorized User. 6 month verification To properly prepare and store radioactive waste material for disposal as described in the UGA/RSM To post proper radiation signs and labels as described in the UGA/RSM

  13. Responsibilities of the Authorized User To treat all authorized use locations as radioactive materialsareas and comply with the associated safety requirements   To ensure that neither radioactive materials nor contaminated equipment is removed from the radioactive materials area, unless proper procedures are followed as described in the UGA/RSM     To ensure that no furniture or equipment is removed from an permitted use location to an unrestricted area until the materials have been surveyed, found to be free of contamination, and all radioactive warning labels removed To provide Radiation Safety with all required radiological records prior to: terminating employment with the University terminating lease of space from the University terminating radioisotope usage

  14. AU Approval, Use and Change Permit Application RSO & RSC Approval PermitMaintenance Changes to Permit Operational Permit Inventory Amendments Surveys Records Waste Training

  15. Chronological Approved Amendments • Possession limits • Change of Location • Inactive or termination status • ARW changes • Sewer Discharge permit

  16. Responsibilities of the Authorized User To properly train and document on the RWC all new personnel before allowing them to work with, or be exposed to ionizing radiation from authorized sources. Training shall include:  Reading of the UGA/RSM General rules of radiation safety Specific rules for the authorized uses and use locations Directions for contacting the Radiation Safety Officer and Radiation Safety staff for assistance      Directions for notifying the proper authorities in the event of an emergency or accident  Certification of at least one worker in the permitted use location as an Advanced Radiation Worker (ARW) by successful completion of required training as provided by Radiation Safety (6 months may be allowed to complete this requirement)

  17. Authorized Usersmust initially train their employeesas Radiation Workers before allowing them to work in a radiation laboratory.

  18. Radiation Worker (RW) Everyone who works under the permit of an Authorized User is a Radiation WorkerIt is the responsibility of the AU to properly train and document new personnel before allowing them to work with, or be exposed to ionizing radiation from authorized sources. All Radiation Worker Training must be documented using form;“UGA Radiation Worker Certification”Available on line at “FORMS”http://www.esd.uga.edu/radOnce completed a copy of this form must be returned to the RSO.The original is for your labs training records

  19. Advanced Radiation Worker(ARW) UGA Advanced Radiation Worker is an individual who through appropriate training and experience is qualified and authorized to work independently with radiation sources and to supervise such use by others, e.g., laboratory radiation technician. Certification is by taking the training modules required by the Radiation Safety Office. After passing an exam for each required module will a person become certified. A minimum score of 70 is required on each exam. If an exam is failed then a retest will be performed. If the retest is failed, then the module must be retaken. A training certificate will be issued upon successful completion of the UGA required Radiation Safety Training.

  20. UGA Radiation Safety Office The Radiation Safety Officer and staff are available to assist and advise Authorized Users of ionizing radiation on the University campus, and to ensure that all ionizing radiation is used in accordance with the policies approved by the Radiation Safety Committee. The RSO shall ensure that proper surveys are carried out in all authorized locations where ionizing radiation is used, and that appropriate records are kept Radiation Safety maintains all records required by state and federal regulations and rules of good practice

In Georgia it is ~ 377.2 mrem

  45. Health Effects of Radiation Ionizing Radiation can directly and indirectly damage DNA DNA Double Helix Acute Exposure Effects Radiation in large doses in a short time causes observable damage ….observable at >25 Rem Chronic Exposure Effects The effects from radiation exposure decrease as the dose rate is lowered. Spreading the dose over a longer period reduces the effects. Much of the controversy over radiation exposure centers on the question of how much damage is done by radiation delivered at low doses or low dose rates. Radiation

  46. Dose Response Model Known Effects Atomic Bomb Survivors Uranium Miners Radium Dial Painters Medical Patients Health Effect (cancer) • Linear No Threshold Dose Curve • Decreased Health Effects Theory • Threshold Dose Theory • Increased Health Effects Theory 4 Theo. Debated Effects 1 2 The NRC and The State of Georgia Follow the Linear No Threshold Theory 3 Dose (rem)

  47. Radiation Dose in Perspective • Health effects are seen only when dose exceeds 25 rem and at a high dose rate • Occupational radiation doses are monitored and limited by law to 5 rem • Based on the LNT model, a worker exposed to 1,000 millirem (one rem) per year for 30 years would lose about 30 days of life expectancy due to increased risk of cancer. • For 95% of the Radiation Users at UGA, doses are too low to measure

  48. A As L Low A As R Reasonably A Achievable A L A R A Philosophy Radiation doses are kept as low as possible Stems from Linear-No-Threshold dose model ALARA program required by Federal and State regulations LNT Model
