A benchmark for Monte Carlo simulations in gamma-ray spectrometry Part II: True coincidence summing correction factors.

The goal of this study is to provide a benchmark for the use of Monte Carlo simulation when applied to coincidence summing corrections. The examples are based on simple geometries: two types of germanium detectors and four kinds of sources, to mimic eight typical measurement conditions. The coincidence corrective factors are computed for four radionuclides.

Reliability of the Modified Ashworth Scale After Stroke for 13 Muscle Groups.

Objective: To evaluate the reliability of the protocol for administration of the Modified Ashworth Scale (MAS) for all commonly affected muscle groups after stroke.

Design: A repeated-measures design was used in administration of MAS for 13 muscle groups on 2 assessment days. Intrarater reliability and interrater reliability (between 3 raters) was assessed.

Validation of efficiency transfer for high-density materials in HPGe spectrometry.

Recycling and conventional reuse of lead materials and structures originating from controlled areas in nuclear facilities rely on historical knowledge and well selected characterization procedures. At the SCK•CEN, one of these procedures involves performing high-resolution gamma-ray spectrometry measurements on several cylindrical shaped test samples (50 mm diameter and approximately 5 mm thickness), obtained during the lead melting campaigns. The high density (11.

Gamma spectrometric measurement of uranium isotopic composition and mass in sintered UO pellets using the efficiency transfer method.

Gamma spectrometric measurements to determine the isotopic composition and total uranium mass in UO pellets (D = 7.5 mm; H = 3.5 mm, ρ = 10 g/cm) were carried out.
