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.
Introduction to Nuclear Medicine. An introductory course in nuclear medicine is usually the first course students take in a nuclear medicine program. Subjects covered include radioactive decay, instruments used in nuclear medicine, radiation types and ways to protect oneself and others from radiation.hese courses are designed to give students hands-on experience in a health care setting. Portions of this course may include working with a current nuclear medicine technologist or other health care professional in order to practice with professional guidance.
