Gloves must be worn from here on out. The user will initiate a log sheet to track the use and disposal of the radiation. Both solid and liquid waste must be monitored and maintained as to the amounts of radioactivity that are disposed of consistent with the log sheet for each lot number or batch of radioactivity. V. REQUIRED TESTS AND RECORDS A. General The Texas Department of Health Bureau of Radiation Control requires that certain tests be made and records maintained on the results of these tests. The requirement for radiation surveys and records of these surveys are covered under the Texas Regulations for Control of Radiation §289 available under Rules and regulations at the TDH web site as well as printed copy available through the RSO. B. Internal Inspections The RSO or the designated alternate shall make periodic inspections of the isotope usage, storage, and disposal records that are maintained in the user’s laboratory to determine whether the user is in compliance with SFASU procedures and state regulations. All laboratories and facilities where radioactive materials are used or stored shall be surveyed periodically in order to detect any changes in radiation levels and to prevent the spread of radioactive contamination. The frequency of these surveys based on the quantity and isotopes in use shall be determined by the RSO as guided by the TRCR. C. Radioactive Waste Disposal The “Radioactive Material Receipt and Disposal” record (RSO form No. 4) for each radioisotope received shall be kept current by the authorized user and forwarded to the RSO upon completion. Form No. 5 shall be completed by the authorized user and sent to the RSI for radioactive material to be disposed of by inclusion in a periodic disposal mechanism carried out by the RSO. D.

A centralized film badge service is available through the RSO to authorized users of radioisotopes. Contact the RSO for initializing or terminating a badge. 3. A centralized file is maintained for all film badge users on campus, thereby enabling the individual exposures to be monitored by the RSO. 4. Requests for exposure records by an employee, such as at the termination of employment, can be furnished. F. Bioassays Bioassays are necessary for anyone using I-125. The current license does not allow I-125 use. VI. DISPOSAL OF RADIOACTIVE WASTE A. General 1. Radioisotopes cannot be destroyed except by natural decay. As a result, the disposal of radioactive waste is strictly governed by federal and state regulations to prevent harm to human and ecological populations. Each radioisotope received at SFASU must be accounted for until it is properly disposed. Each authorized user accomplishes this by completing "Radioactive Material Receipt and Disposal" record (Form No. 4). When disposing of radioactive waste, the method and amount of disposal must be documented on Form No. 4. There are four methods approved for disposal of radioactive waste at the SFASU. Each disposal shall meet the requirements of the state and federal laws applicable to each case. These methods are as follows: a. Disposal into the sanitary sewer system (Not applicable to site 001 until all levels of radiation are decayed to background levels and considered Deleted: ). to be decayed. b. Disposal by radioactive decay. c. Release into the atmosphere. d. Shipment to a designated commercial burial area. B. Disposal into the Sanitary Sewer System (site 000 only) No radiation will be disposed of at site 000. Revised 051408 12 Deleted: other than sealed sources will be used C. Disposal into a Septic System (site 001) No radiation may be disposed of into a septic system. All radiation must be decayed to ≤ to background. D. Disposal by Radioactive Decay 1. Radioactive waste may be held for approximately 10 half lives to allow decay to safe levels. Short half-life radioactive waste (t ½ < 3 days) may be kept on site for decay and disposal by the user. The radioactive waste should be labeled and dated. After approximately 10 half-lives, a survey shall be made to assure decay to undetectable levels has occurred. The waste may then be disposed of without regard to its radioactive properties. Labels must be removed prior to disposal in local landfill. Deleted: ½ < 2. Longer half-life radioactive waste (3 days > T ½ < 100 days) may be placed in storage for decay prior to final disposal. Each user should package solid waste in plastic bags in as compact a manner as possible. Each package should contain radioactive waste identified by date, radioisotope, and activity and should be listed on "Radioactive Waste for Pickup by RSO" (RSO Form No. 5). Radioactive material will be stored in the designated area for each building in which the use of radioisotopes is authorized. The RSO will monitor the air quality and external radiation levels of this building at monthly intervals to ensure that limits are kept within allowable limits as defined in TRCR. 3. Liquid radioactive waste should be packaged in non-breakable containers or, if packaged in a breakable container, the secondary container should have a sufficient amount of absorbent material to absorb all of the liquid in the event of primary container breakage. 4. Each package should contain radioactive waste identified by date, radioisotope and activity and should be listed on "Radioactive Waste for Pick-up by RSO" (RSO Form No. 5). The RSO shall be notified and pickups of packages will be made weekly. The radioactive waste will be transported to a storage site for decay. All radioactive warning labels must be removed prior to disposal. Records will be maintained by the RSO of each disposal container including checks to ensure such material is no higher than background prior to disposal. D. Release into the Atmosphere The following restrictions shall be observed when releasing radioactive gas or vapor into the atmosphere: 1. Disposal of radioactive gases shall be made in a properly functioning laboratory hood. 2. The concentration of the gaseous waste shall be diluted to values that are in compliance with Texas Regulation for Control of Radiation, §289.202(ggg)(2)(F), prior to release to an unrestricted environment. 3. Each proposal involving airborne release of radioactive material shall be submitted to the RSO for analysis to assure that prior to any airborne releases meets the above conditions with review and approval with the TDH Bureau of Radiation Control. Revised 051408 13 E. Burial (Off-Site) Long-lived solid radioactive wastes and liquids, which cannot be released to the sanitary sewer system or held for storage/on-site decay, shall be shipped to a designated commercial burial site. F. Exemptions 1. All radioactive waste must be disposed of properly by one of the four methods described above. However, in order for the system to function properly, the volume of waste must be kept to a minimum. Therefore, do not mix non-radioactive waste with radioactive waste. This can be determined by a survey prior to packaging radioactive waste. 2. For 14C and 3H, liquid waste concentrations below 0.05 µCi / ml or gram are exempt from regulations concerning disposal of radioactive waste. All samples below this concentration may be disposed of without regard to their radioactive properties, but such disposals must be recorded. G. Facility Decontamination 1. It shall be the responsibility of the authorized user to decontaminate any laboratory facility, which becomes contaminated. Also, upon vacating all premises where radioactive materials have been used, the authorized user shall ensure that all residual radioactivities is properly removed and disposed of in accordance with the Texas Regulations for Control of Radiation and this Handbook. Please contact the RSO or his designated assistant if your waste disposal problem is not covered by any of the above-mentioned alternatives. VII. SURVEY PROCEDURES A. Introduction The RSO and his designated assistant shall, in general, make routine surveys of various labs and areas where radioactive material is handled. The purposes of these surveys are to: 1. Determine areas of high radioactive exposure. 2. Determine areas of removable contamination and decontaminate the area. These procedures are defined as area surveys and wipe test surveys and are described below: B. Area Surveys 1. Survey Frequency Frequency of survey will be followed as designated below unless there appears to be a significant recurrent problem with storage in one particular area (i.e., contamination of surfaces). Such an area will be surveyed as a high level area until the exposure limit is reduced. Revised 051408 14 1. Surveys will be done immediately following the use of any radioisotope in a given area according to the guidelines of the TRCR by wiping with a piece of dry filter paper of cotton swab in a 100 cm2 area and counted in scintillation cocktail under conditions specific for the particular radioisotope being monitored. 2. Method of Survey Sketches of various labs submitted with the license application shall be used to survey areas where radioactive materials are stored or are handled. A survey meter capable of measuring as little as 0.1 mR / hr will be used in the designated areas. 3. Acceptable Limits Areas where the radiation level exceed the limits set forth in §289.202(ggg)(6) are considered unsafe. Steps shall be taken to reduce the exposure to a level considered safe for restricted areas. These steps will include additional shielding and decontamination if necessary. It is the policy of this institution to practice the safe handling and storage of radioactive materials and to achieve exposure levels that are as low as reasonably achievable. It is, therefore, a safe practice to monitor areas after each use where radioactive materials have been handled. C. Wipe Test Surveys 1. Survey Frequency Surveys will be carried out immediately following any use of radioisotopes with the exception of sealed sources. When there appears to be a significant problem with contamination in one area, this area will be treated as a high level area and surveyed until no contamination is found. 2. Method of Survey a. Sketches of various labs submitted with the license application shall be used to survey areas predisposed to contamination. b. Wipe tests using filter paper or cotton swab will be counted in a suitable counter. 3. Acceptable Limits Wipe test surveys are considered safe if they do not exceed 100 dpm per 100 cm2. Any areas above this level will be considered contaminated. The area will be decontaminated under the direction of the RSO. VIII. EMERGENCYPROCEDURES A. General In the event of an emergency involving radiation, contact the RSO for clean up and monitoring. Revised 051408 15 It is the policy of SFASU to follow the ALARA principle, to keep all exposure as Low As Reasonably Achievable (ALARA). A radiation incident is defined as any unplanned exposure or spill of radioactive material. Such incidents should be reported immediately to either the RSO or other designated personnel according to "The Radiation Incident Emergency List" which is to be posted in each area using radioisotopes. The RSO or his designated assistant will direct and monitor any action necessary to minimize further exposure of personnel, the clean-up of any contaminated areas, and the interaction with hospital personnel in the case of any injuries. B. Decontamination If at all possible all clean-up activities should be directed by the RSO. If the RSO or his assistant is not immediately available the following procedures should be followed: 1. Call the RSO or designated emergency personnel as designated on the Radiation Incident Emergency Call List. 2. Life saving and vital first aid to injured personnel have the highest priority. In the case of injury, or suspected injury, a call should be placed to the SFASU Health Clinic. The physician in charge should be informed of the whereabouts of the victim and of the potential contamination by radioactive materials. The physician will then determine the action to take. 3. The spill should be contained immediately by dropping paper towels or other absorbent material onto it. 4. Put on impermeable gloves (double glove is recommended). 5. Check shoes for signs of contamination. If any contamination is evident they should be removed prior to leaving the area. 6. The entire area of potential contamination should be marked off and guarded to prevent any spread of contamination or further exposure of personnel. 7. All evacuees should be detained in an area where they can be surveyed by the RSO. 8. In general, clean-up should not be attempted by inexperienced personnel. If the RSO is not immediately available as few people as possible should be involved in the clean-up and should follow the following procedures: a. Impermeable gloves, shoe covers and safety goggles should be worn. b. The spilled material, taken up with absorbent paper, should be placed into a waterproof bag immediately using tongs or forceps. Once as much contamination as possible has been removed in this way the area should be sprayed with RADCON and wiped with towels held in forceps always working towards the center of the area of contamination, rather than away from it, to minimize the spread of contamination. c. A survey meter should be available and used to monitor clean-up efforts. A person not directly involved in the clean up to prevent its contamination Revised 051408 16 should use this. The probe itself should be covered in plastic film to prevent inadvertent contamination. d. Clean-up should proceed until levels several times above background are achieved. Higher levels can be covered with shielding and marked with Radiation Warning tape until the RSO is available to make an assessment for further action. e. When the operation is complete all gloves and other protective equipment should be monitored for contamination and if any is found, they should be left with other contaminated material in plastic bags for eventual disposal by the RSO. f. The responsible Principal Investigator should submit a written report of the incident to the RSO within 24 hours outlining the incident, the circumstances leading up to the incident, the action taken and future procedures to prevent any re-occurrence. g. The RSO will survey the area and perform wipe tests before the area is returned to normal use. Revised 051408 17 Emergency Notification and Assistance Radiation Safety Officer for Stephen F.
