what is the biological,chemical and physical properties of fly ash when it is use as a carrier
Yes. Ammonia is a natural bi-product of some biological properties. Most of this ammonia is converted into urea.
Isosteric compounds have the same number of atoms and/or the same number of valence electrons in total. Their electrons may be arranged in the same way. The physical properties of isosteric compounds are similar but their biological properties may be very different.
The gamma radiation is very penetrant in biological tissues.
yes. If radionuclides are released into the environment, through accident, poor disposal, or other means, they can potentially cause harmful effects of radioactive contamination. They can also cause damage if they are excessively used during treatment or in other ways applied to living beings. This is called radiation poisoning. Radionuclides can also cause malfunction of electrical devices.
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

Radionuclides can be very hazardous to living things. It can damage the tissues and cause irreversible changes to the cells.
no
radionuclides
No, they differ in biological activity because a specific arrangement of atoms in a specific enantiomer may react with a particular enantiomer of another compound present in biological systems while other does not.
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.
Dissolved salts have an influence on the physical, chemical and biological properties of the solution.
Water is a very good solvent.
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)
