TRAINING

Understanding Radiochemistry Testing and the TNI 2016 Standard - ASTM D7283 and EPA 906.0 (Liquid Scintillation Counting)

Friday August 10, 8:00am - 5:00pm

Using ASTM Method D7283, ASTM Standard Test Method for Alpha and Beta Activity in Water By Liquid Scintillation Counting, and EPA Method 906.0, Tritium in Drinking Water, as examples, this course will provide participants with a general understanding of the theory behind the radioanalytical techniques used, and applicable requirements of TNI 2016 Standard Volume 1 Module 6 (V1M6). A mixture of theory-lecture and interactive exercises using real laboratory data examples will help participants see how analytical processes translate into actions, results, and records that one might encounter in a typical radioanalytical laboratory. It will also address typical challenges that may be encountered. This class will be of benefit both to radiochemistry laboratorians and radiochemistry assessors. Topics addressed will include:

  • Method scope, application, and limitations;
  • Radioactive decay;
  • Radiochemical preparation;
  • Sample test source preparation;
  • Liquid scintillation counter (LSC) set-up, performance checks, efficiency and cross-talk calibrations, and background determinations;
  • Calculation and reporting of results and associated statistics (i.e., counting uncertainty vs. combined uncertainty, critical level vs. minimum detectable concentration vs. SDWA Detection Limit, chemical yield);
  • Common problems and challenges encountered with these methods;
  • TNI Standard Volume 1, Module 6 requirements as they relate to the two methods.
