The primary techniques that employ ¹⁴C in histology include autoradiography and liquid scintillation counting. Autoradiography involves placing a biological sample containing ¹⁴C in close contact with a photographic film or a digital detector. The emitted radiation creates an image that reveals the distribution of the radioactive isotope within the tissue. Liquid scintillation counting, on the other hand, measures the radioactivity of a liquid sample containing ¹⁴C, allowing for quantitative analysis.
