Evaluation on the Counting Efficiency of a Chair-type Whole Body Counter for Accident Monitoring of Internal Contamination
Major accidental release of radionuclides has the potential for significant radiation exposure in large populations.[1] Rapid monitoring for internally contaminated people is required in radiation accident. If the release contains radionuclides which emit high energy gamma ray, the most suitable mean of providing this monitoring is Whole Body Counter(WBC).[2] Chair-type WBC is more suitable tha...
متن کاملEvaluation of Detection Characteristics for Scanning-Type Whole-Body Counter
As an alternative to the phantom used for calibrating whole-body counters, in this study the Monte Carlo simulation was used to evaluate peak efficiencies for a whole-body counter installed at the JNC, to examine the validity of using the simulation technique to calibrate the whole-body counter. Prior to simulating a phantom, the sensitive region of the crystal in the Ge detectors which are use...
متن کاملAn Automated Shielded Chair Whole Body Monitor
Whole body/organ counting plays an important role in assessing, limiting and controlling the intakes of radioactive materials by the workers of a nuclear research centre as well as of nuclear industry. The Internal Dosimetry Division of BARC, besides designing, developing, supplying and installing the whole body/organ counting facilities at DAE’s nuclear installations, also operates such facili...
متن کاملMathematical Calibration of a Whole-Body Counter
This paper describes the mathematical efficiency calibration of the whole-body counter at Forschungszentrum Jülich using Monte Carlo codes and mathematical anthropomorphic phantoms. As a prerequisite for the Monte Carlo simulations a precise model of the 4 high-purity germanium (HPGe) detectors had to be developed. Because the technical data provided by the manufacturer were not sufficient for ...
متن کاملBetter Counter-measures for Curtailing Whole Body Retention of Radiostrontium
Accidents are always sudden. They happen despite considerable developments in the safety techniques/warning systems, affecting not only the workers directly involved, but also the people around. This is evident from the reported article on the 15th anniversary of the Chernobyl nuclear accident, entitled: “15 years on, Chernobyl survivors relive the nightmare” by Philippe Coumarianos (Times of I...
