Summary of "Monte Carlo simulation of an HPGe detector for detection of Pu in waste assay system."

This paper discusses the modeling of HPGe detector used in waste assay system using Monte Carlo code FLUKA to determine its detection limits. The modeled detector is validated using experimental point sources efficiencies in the energy range 60 keV-2000 keV. The numerical estimation of efficiency values for Pu present inside a 230 L cotton filled waste drum at various locations along the axis of the detector is discussed. Estimation of the minimum detectable activity (MDA) for Pu at these locations in the presence of 1 MBq of Cs/Co again along the axis of the detector is examined. The efficiency of Pu decreases from 6.1 × 10 to 7.5 × 10 cps/Bq as the location of Pu moves away from the detector. MDA of Pu increases as the position of Pu and Cs/Co in the waste drum shifts away from the detector while it decreases as the location of Cs/CO moves away from Pu along measurement axis. It is observed that for all locations of Cs/Co with Pu located up to 200 mm from the edge of the drum, the detection limit is within 140.3 mg (allowed limit).

Medical and Biotech [MESH] Definitions

In statistics, a technique for numerically approximating the solution of a mathematical problem by studying the distribution of some random variable, often generated by a computer. The name alludes to the randomness characteristic of the games of chance played at the gambling casinos in Monte Carlo. (From Random House Unabridged Dictionary, 2d ed, 1993)

A computer simulation technique that is used to model the interaction between two molecules. Typically the docking simulation measures the interactions of a small molecule or ligand with a part of a larger molecule such as a protein.

A genotoxicological technique for measuring DNA damage in an individual cell using single-cell gel electrophoresis. Cell DNA fragments assume a "comet with tail" formation on electrophoresis and are detected with an image analysis system. Alkaline assay conditions facilitate sensitive detection of single-strand damage.

Waste products which, upon release into the atmosphere, water or soil, cause health risks to humans or animals through skin contact, inhalation or ingestion. Hazardous waste sites which contain hazardous waste substances go here.
