Question

Quizplus · Accepted Answer

When a photographic emulsion is brought into close contact with a radioactive source, the particles emitted by the source interact with the silver halide crystals in the emulsion. This interaction results in the formation of tiny, black silver grains in the emulsion after photographic development. This process is called autoradiography and is used in various fields, including medical imaging and biology research, to visualize the distribution of radioactive isotopes in a specimen.
