Responsibilities

The Radiation Protection Department (RPD) at SLAC is responsible for providing oversight for the safe operation of all radiological work at SLAC and performs shielding calculations for beam lines, experiments and facilities. RPD Health Physicists identify potential sources of ionizing radiation for existing and new experiments and projects and define radiation protection measures to minimize the exposure to personnel and the impact to the environment. The mission of RPD also includes but is not limited to: managing the operational Radiological Protection Program at SLAC, monitoring of the occupational exposure of personnel, radiological environmental protection program, and management of radioactive materials, sources and of low-level and mixed radioactive waste. The staff of Radiation Physics Group (RPG) in the RPD will participate in radiation protection studies to develop and optimize measures that protect personnel, environment and equipment for various facilities and projects which include the Linac Coherent Light Source (LCLS), the Stanford Synchrotron Radiation Laboratory (SSRL) at SLAC, and the International Linear Collider (ILC). RPG staff members are responsible for radiological considerations and operational aspects of the facilities to which he/she has been assigned. The main responsibilities of this position will be to: 1) ensure the safe radiological operation of beams by a. working closely with experimenters, engineers, and accelerator physicists in safety design of experiments and beam lines b. calculate radiation dose rates under various beam loss and shielding conditions c. assist in calculating heat loads for critical devices, e.g., beam stops, collimators, etc., d. assist in the design of the Personnel Protection System (PPS) and Beam Containment System (BCS),* e. supervise initial radiation measurements and establish area monitoring at new beam lines*, and f. work closely with RP Field Operation Group personnel in monitoring routine radiological operations at SLAC.* 2) assist accelerator physicists on all radiation protection aspects of machine design, operation, and maintenance of the accelerators. 3) develop and maintain radiation transport codes to be used for detector design, machine development, induced radioactivity, shielding, and dosimetry. 4) perform shielding calculation, induced radioactivity and dose to personnel, equipment and environment using Monte Carlo computer codes. 5) assist experimenters in determining causes of their radiation backgrounds and in designing shields to minimize the problem. 6) assist engineers and physicists in avoiding or minimizing radiation damage problems by performing calculations and providing high-dose dosimetry services in the mega rad range. 7) participate actively in research and development activities in radiation/health physics in support of overall SLAC mission; publish R&D results and participate actively in professional meetings, and development opportunities in the field. 8) document radiological protection measures for submittal to regulatory agencies at each stage of the design, commissioning, and operation of the new facilities * 9) provide support and oversight for safe radiological operations at accelerators and beam lines by creating procedures and establishing protocols (e.g., Beam Authorization Sheets), in conjunction with the cognizant safety offices in line organizations * 10) as needed, participate in committees (internal and external) that develop and review the radiation protection programs.* 11) participate in the development of the radiation protection program at SLAC, which involves the study of codes of federal regulations, DOE orders, state and local regulations and internal policies and procedures, and writing technical basis documents. **If the successful candidate has sufficient expertise to perform the full range of responsibilities independently, hire at the 3P4 level.
