B Radioactive tracers are used in detecting blood clots.
D Radiation is used to remove unwanted accumulated electric charge in machinery.
Some of the uses of radioactivity and radioactive substances are: - Tracers such as radioactive salts of sodium and iodine are used to detect tumours and blood clots in bodies.
- α and β rays are used to remove any unnecessary accumulated charge on machinery in factories and industries.
- The carbon - 14 isotope, 146C is used to estimate the age of archaeological entities such as rocks and fossils in a process known as carbon dating.
- α - particles are used as projectiles to initiate nuclear reactions in atomic energy reactors.
