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.
On average, every Australian can expect to have a nuclear medicine procedure that uses a radioisotope for diagnostic or therapeutic purposes at some stage in their life. Nuclear medicine and radiology are the medical techniques that involve the use of radiation or radioactivity to diagnose, treat and prevent disease.While radiology has been used for close to a century, the term nuclear medicine began to be used around 50 years ago.Discover more.uclear power has been in use for decades and is one of the fastest growing energy options for countries seeking energy security and low-emission energy solutions. Globally nuclear power is the only proven base-load energy option available that has low carbon-dioxide emissions.
