In which technique is radioactivity detected by mixing the sample in a vial with a special fluid that contains compounds that emit light if struck by a beta particle?
A)autoradiography
B)an NMR machine
C)liquid scintillation spectrometry
D)mass spectrometry
E)AFM

Question

Quizplus · Accepted Answer

Liquid scintillation spectrometry involves mixing a sample with a scintillation fluid that emits light when struck by beta particles. The amount of light emitted is proportional to the amount of radioactivity in the sample, allowing for quantification. This technique is commonly used in radioisotope dating and tracer experiments.
