Alpha–electron and alpha–photon coincidences in high-resolution alpha spectrometry
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006Abstract Photons and electrons emitted in coincidence with an alpha particle distort the ideal peak shape and may lead to spurious identifications and incorrect activity estimation. Simulations are used here to establish the role of coincidences in high-resolution alpha spectrometry using 241Am as an example.

Some educational applications of alpha spectrometry
European Journal of Physics, 1992The most difficult task in alpha spectrometry is perhaps making the source to be measured, but once sources are prepared, the gathering and analysis of results is an activity which can be developed in undergraduate laboratories. Energy calibration, determinations of counting yield and energy resolution, calculation of areas under the peaks in the ...

Determination of boron in glass by alpha-spectrometry
Journal of Radioanalytical and Nuclear Chemistry Letters, 1994Alpha-spectrometric method has been used for the determination of boron in borosilicate glasses. For irradiation thermal neutrons with a flux of about 105 n·cm−2·s−1, produced in a paraffin moderator surrounding a deuteron target of a small neutron generator, were used.

Routine alpha-spectrometry of environmental samples
International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1987Abstract A laboratory for routine alpha-spectrometry based on gridded ionisation chambers (80, 500 and 20,000 cm 2 of source area, respectively) has been built for direct measurement of low specific activity samples. They allow direct spectrometry of samples having specific activities as low as 6.7, 2.5 and 0.18 mBq g −1 , respectively.

Alpha spectrometry in emergency preparedness
2020A study to assess the choice of science as a vocation and career, considering alpha spectrometry in emergency preparedness, was carried out. The development of a career or a vocation by any individual in the field of science could better be achieved through consolidated plan towards a goal.

Alpha-spectrometry in nuclear fuel analysis
Journal of Radioanalytical Chemistry, 1974A survey is given of the analysis of actinide nuclides by means ofa-spectrometry in high-level radioactivity process solutions resulting from reprocessing of spent U-Th fuel. Separation of fission products and isolation of the nuclides228Th,231Pa,232U,237Np and238Pu are performed by adsorption, ion-exchange, extraction chromatography and extraction ...

Alpha-particle spectrometry and its applications
The International Journal of Applied Radiation and Isotopes, 1984Abstract Alpha-particle spectrometry is a precise and sensitive technique which has many applications in the nuclear-energy field. Using a thin, uniform source with a suitable detector and ancillary electronic equipment, the constituents of a mixture of α-emitting nuclides can be accurately assayed both at activity levels found in the environment and

Liquid scintillation alpha spectrometry techniques
Nuclear Instruments and Methods in Physics Research, 1984Abstract Accurate, quantitative determinations of alpha emitting nuclides by conventional plate counting methods are difficult, because of sample self-absorption problems in counting and because of non-reproducible losses in conventional sample separation methods. Liquid scintillation alpha spectrometry offers an attractive alternative with no sample
