How often to water and fertilize: While growing, cacti and succulents should be watered at least once a week. Some people water more often than this. During each watering, give the soil a good soaking, so that water runs out of the 'drainage holes' of the pots. During the growing season, a balanced fertilizer, which has been diluted to 1/4 strength, can be added to the water for each watering.
Explain the scientific and technical concepts related to nuclear medicine. 1  Nuclear medicine is a specialized branch of modern medicine that exploits the process of radioactivity for imaging, diagnosis, and treatment. Many imaging techniques inject small amounts of radioactive material into the body, which are then tracked by a sensing device specific to the type of radiation emitted from that material.
â¢ Nuclear medicine imaging uses safe, painless, and cost-. effective techniques to image the body and treat disease. â It uses very small amounts of radioactive pharmaceuticals and. traces their progress through your body. â Nuclear medicine is unique, because it helps doctors âviewâ how. your body is functioning. â¢ This is different from x-rays or CT scans, which show how your body. looks rather than how it works. â¢ Nuclear medicine therapy uses larger amounts of radiation to. treat thyroid disease and cancer.
