The EUROMET project 428 examines efficiency transfer results for Ge gamma-ray spectrometers when the efficiency is known for a reference point source geometry. For this, different methods are used,… (More)

This paper describes the application of alpha-particle counting at a defined low solid angle and of high-resolution alpha-particle spectrometry at IRMM. These techniques are used in the frame of… (More)

A succinct overview is presented of primary standardization methods for activity. They have been subdivided into high-geometry (4π or 2π) methods, defined-solid-angle counting methods and coincidence… (More)

A Peltier-cooled silicon drift detector was successfully applied for conversion electron spectrometry. The energy resolution of the detector for 45 keV electrons was 0.50 keV (FWHM). The approximate… (More)

The apparent tendency to underestimate the uncertainty of experimentally determined half-life values of radionuclides is discussed. It is argued that the uncertainty derived from a least-squares… (More)

Count loss through a cascade of pile-up and dead time is studied. Time interval density-distribution functions and throughput factors are presented for counters with a series arrangement of pile-up… (More)

Specific uncertainty components of counting at a defined solid angle are discussed. It is potentially an extremely accurate technique for primary standardisation of activity of alpha emitters and… (More)

Alpha-particle spectrometry is routinely performed with the aim of measuring absolute activities, activity ratios between different alpha-emitting nuclides or decay data such as branching factors,… (More)

An electron spectrometry set-up was built at IRMM consisting of a vacuum chamber with a moveable source holder and windowless Peltier-cooled silicon drift detector (SDD). The SDD is well suited for… (More)

Least squares fitting procedures and weighted averages imply the assignment of proper weighting factors to the stochastically distributed data involved. In the case of a Poisson distribution, the… (More)
