Question

Quizplus · Accepted Answer

Radioisotopes are sources of radiation as they emit radioactive particles, which can lead to the ionization of surrounding atoms and molecules, causing damage to cells and tissues. Heterocyclic amines are chemicals formed during the cooking of protein-rich foods at high temperatures, but they are not sources of radiation. Ultrasound tests use sound waves to produce images of internal organs and tissues, which do not involve ionizing radiation. Television screens emit low levels of radiation, but not at levels typically considered harmful.
