How can radioactivity be measured

Web6 de mar. de 2024 · Radioactive isotopes are often used to date samples of material. Organic substances can be dated by measuring the amount of carbon-14 they contain, while the age of a sample of rock can be determined by comparing the amounts of various radioactive isotopes present. This technique has allowed scientists to measure the age … WebAirborne contamination is measured by specialist radiological instruments that continuously pump the sampled air through a filter. Airborne particles accumulate on the filter and can be measured in a number of ways: The filter paper is periodically manually removed to an instrument such as a "scaler" which measures any accumulated radioactivity.
