Lecithin is an organic compound.
Is shampoo organic or inorganic?
organic
Is C8H18O organic or inorganic?
Compounds having this molecular formula are organic compounds.
Is newspaper organic or inorganic?
Paper is mostly cellulose, which is organic.
Is lipase organic or inorganic?
Lipids are energyrich organic compound made of cordon, hydrogen and oxygen. Lipides contain more energy than carbohydrates. :D
Who treats diseases with radionuclides?
radiologist
What effect do radionuclides have on living things?
Radionuclides can be very hazardous to living things. It can damage the tissues and cause irreversible changes to the cells.
What substances used in radiology that emit radiation?
radionuclides
What is cosmogenic radionuclides?
Cosmogenic radionuclides are isotopes produced by interactions between cosmic rays and atoms in the Earth's atmosphere or surface. These radionuclides are formed at a relatively constant rate and provide valuable information about Earth processes, such as erosion rates, sediment transport, and glacial activity. They are commonly used in geology, archaeology, and atmospheric science to date events or processes that occurred in the Earth's past.
What are the biological properties of radionuclides?
Biological properties - 1. Radionuclides cannot be destroyed or degraded, unlike organic substances as such - a. Because radionuclides cannot be destroyed, disposal of residual radioactive wastes are usually very technical and limited. The waste forms must meet disposal site waste acceptance criteria. b. The storage is also a problem 2. They are able to be put into the body easily (injection, inhalation, ingestion) 3. They have mimic behaviour of biological material, as such they are able to be 'stuck to' a biological material for a specific test (labelling) 4. They have short physical half-life, thereby decay quickly. But long enough to be produced and delivered to the exam site
What are the two radionuclides which concentrate on seafood?
Although Mercury can be found in fish and shellfish the two radionuclides which concentrate in seafood are Lead-210 and Polonium-210. (Source: FEMA Radiological Emergency Management Course IS-3)
What happens to the water from a decommissioned nuclear power plant?
During the cooling process, the water becomes contaminated with radionuclides – unstable atoms with excess energy – and must be filtered to remove as many radionuclides as possible. The filtered water is then stored in huge steel tanks or released into nearby bodies of water.
What type of imaging uses low level radionuclides to locate and stage tumors?
Radionuclide Scanning (nuclear Medicine Scanning)
What diagnostic procedure uses positive radionuclides to reconstruct brain sections?
Positron Emission Tomography (PET) is a diagnostic procedure that uses positive radionuclides to reconstruct brain sections. By tracking the positron-emitting tracer molecules, PET can create detailed images of brain metabolism and function.
What is the difference between radioisotopes and radionuclide?
Radioisotope and radionuclide are often used interchangeably, but there is a subtle difference. A radioisotope is a type of isotope that emits radiation, while a radionuclide is an atomic nucleus that is unstable and emits radiation. In essence, all radioisotopes are radionuclides, but not all radionuclides are necessarily radioisotopes.
What is nuclear chemotheraphy?
Some radionuclides used in nuclear medicine can emit radiation that kills cancer cells. There are also pharmaceuticals that behave a certain way in the body (like accumulating in the thyroid). By attaching the radionuclides to the pharmaceuticals, we can "spot" treat things like thyroid cancer without giving a big radiation dose to the rest of the body.
Contribution of nuclear energy in the field of medicine?
By using nuclear reactors, it is possible to create a variety of radionuclides that have use in medicine. These are used for diagnosis and for therapy. Diagnostic radionuclides are used for imaging. This is a process rather like taking an X-ray, except that the source of the radiation is within the patient. For example, if a patient has a problem with the thyroid gland, a radionuclide such as 99mTc can be used in a chemical compound that is concentrated in the thyroid gland. Then, by recording the emissions, an image of the gland can be made. In this case, the technetium has a very short half-life (6 hours), so exposure to it is short, and the emission is a gamma ray, which is less destructive than other alternatives. Some other radionuclides are used for therapy. In these cases, radionuclides can be chosen that have emissions that do not penetrate tissue deeply. These can be put into molecules that concentrate in a part of the body, typically cells in a tumor, targeting that particular body of cells to be destroyed. In this way, it is possible to eliminate a tumor that might be inoperable by surgery.
