scintillation counter

n
(General Physics) an instrument for detecting and measuring the intensity of high-energy radiation. It consists of a phosphor with which particles collide producing flashes of light that are detected by a photomultiplier and converted into pulses of electric current that are counted by electronic equipment

Samples are collected at different positions of spherical radius, prepared, and measured with different analytical devices, that is, the multi-channel y counter, liquid scintillation counter, and total [alpha]/[beta] counter.
Radiometric survey was carried out using Geiger-Muller counter to record total ambient surface radiations and Scintillation counter to note the surface gamma radiations along the eight selected profiles where VLF survey was performed.
METHODS: A total of 433 healthy ambulatory Caucasians (253 men and 180 women) aged 18--94 y were measured by dual-energy X-ray absorptiometry (DXA) and whole body scintillation counter (TBK counter) using a large sodium iodide crystal (203 mm diameter).
Counting was done in liquid scintillation counter (Packard Tricarb, Liquid Scintillation Spectrometer).
One mmol of breath C[O.sub.2] was collected at 10, 15 and 20 min and radioactivity measured using liquid scintillation counter.
After a supplementation with 5 ml scintillation mixture, the isotope uptake of each sample was determined in a Beckman scintillation counter.
