The results of research on the application method measurement gross alpha-, beta-activity in water using liquid scintillation counter (LSC) Quantulus 1220 are presented. Basic procedures preparation and spectrometric aqueous samples were studied performed. detection efficiency beta-particles depending quenching optimum beta-radiation separation parameter for used determined. Testing validation ...

the activity concentration of gross alpha and gross beta particles in four samples of borehole drinking water consumed in ibrahim badamasi babangida university (ibbu), lapai, niger state-nigeria was measured, using a portable single channel gas free proportional counter (mpc2000b-dp) detector. this study focused on cancer related problems and the bio-data of the environment was discussed as wel...

miniBELEN is a modular and transportable neutron moderated counter with nearly flat detection efficiency up to 10 MeV. Modularity implies that the moderator can be reassembled in different ways order obtain types of response. The detector has been developed context Measurement Alpha Neutron Yields (MANY) collaboration, which scientific effort aiming carry out measurements (

We demonstrate a wide-field alpha-particle imaging system based on the detection of alpha-induced scintillation light from ZnS:Ag screen using an EMCCD camera. develop efficient image processing algorithm to remove cosmic and thermal noise locate alpha particle interactions in images. This is particularly suited low-activity samples where long acquisition periods entail large number frames with...
