D)mass spectrometry
E)AFM

Question

Quizplus · Accepted Answer

Liquid scintillation spectrometry is the most sensitive and widely used technique for quantifying the radioactivity of a specimen. It involves mixing the sample with a liquid scintillation cocktail, which becomes fluorescent when it interacts with radiation emitted by the specimen. The amount of radioactivity in the sample is then measured by detecting the intensity of the fluorescence. This technique can detect and quantify very small amounts of radioactivity with high accuracy and precision.
