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 part of speech is the word biological?
Biological is an adjective.
What is the origin of the term Electrophysiology?
Electrophysiology is of Greek origin. It is the study of electrical properties of biological cells and tissue. It measures voltage change or electric currents on many scales like ion channel protein to organs like the heart.

What is the simple definition of mononucleotide?
mononucleotide...mono means one and nucleotide means biological molecule so simply one biological molecule.
What is the definition of special properties?
The definition of special properties are the unique features of a substance. They are commonly derived from other intrinsic and extrinsic properties.
What are the biological properties of radionuclides - slide11?
Radionuclides possess unique biological properties that significantly impact their behavior in living organisms. They can emit ionizing radiation, which can cause cellular damage, alter DNA, and lead to mutations or cancer. The type of radiation (alpha, beta, or gamma) influences their biological effects, with alpha particles being the most damaging when ingested or inhaled, while beta and gamma rays can penetrate tissues more effectively. Additionally, certain radionuclides can accumulate in specific organs or tissues, affecting their biological pathways and overall health outcomes.
What are the radiological properties of radionuclides?
Radionuclides exhibit distinct radiological properties based on their mode of decay, which can include alpha, beta, or gamma radiation. Alpha emitters tend to have low penetration power and can be stopped by a sheet of paper, while beta particles can penetrate further but are still relatively weak against materials like plastic or aluminum. Gamma rays, on the other hand, are highly penetrating electromagnetic radiation that requires dense materials like lead for effective shielding. Additionally, the half-life of radionuclides determines the duration of their radioactivity and influences their applications in fields such as medicine and energy.
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
Do Molecules have a rigid and inflexible three dimensional shape which contributes to their biological properties?
no
Why are enantiomers of biological interest?
Mainly because enantiomers have identical physical and chemical properties. However, the difference between two enantiomers can have tremendous impact, especially in biological systems, because many important biological molecules are chiral.
Which elements have several properties?
Carbon, hydrogen, oxygen, and nitrogen are examples of elements that have several important properties due to their versatile bonding capabilities and prevalence in biological molecules. These elements play crucial roles in various chemical reactions, biological processes, and the formation of organic compounds.
What 3 types of properties does water have?
Water has chemical properties, such as being a polar molecule; physical properties, such as high surface tension and specific heat capacity; and biological properties, such as being a universal solvent and essential for life.
What is biological properties?
Weighted training vests are specialized pieces of equipment for serious body builders and intermediates looking to take it to the next level. Check online at a site like Beachbodysupply.com, they have several weighted vests in different price ranges.
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 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)
