HP-606-5 Internal Dosimetry and Gamma Spectroscopy

HP-606-5 - Practical Applications of Internal Dosimetry and Gamma Spectroscopy

Prerequisites:
A fundamental understanding of the principles of radioactivity and radioactive decay is required. Some familiarity with whole body counting and/or in vitro bioassay is helpful but not required.

Description:
This five-day course presents the principles of Internal Dosimetry and bioassay, and an introduction to gamma spectroscopy in a practical format which can be applied to the working environment. This course takes the student through the fundamentals of internal dosimetry to the analysis of actual internal intake incidents. The focus of this course is the utilization of bioassay results in the determination of intake and dose. The design of a practical bioassay program, including routine and incident monitoring frequencies and data quality, is discussed in detail. A significant amount of time is devoted to calculations using actual intake scenarios. Practical applications of data are stressed. Students are invited to bring scenarios for review during the class. The student will become familiar with the use of current documents and references. These documents include, but are not limited to: NUREG/CR-4884, ICRP-30, ICRP-26, EPA Report 520, ICRP-66, ICRP-68 and 10CFR20. For on-site courses, methods specific to site procedures can be stressed.

Who should attend:
Health physicists, radiological engineers and others who are involved in dose assessment, regulatory compliance, supervision of internal dosimetry programs and quality assurance oversight will benefit from the practical approach of this course. On site courses, of shorter duration, which are directed to technicians/ operators are available. AAHP CEUs are available for this course.
