Applications
(i) Radioactive dating This gives us an approximate age of the rock or material containing the radioactive atoms. For e.g., A measurement of a fraction of uranium atom which have decayed into lead (by knowing the half life of uranium) tells us how old the rock is. (ii) Radiat..
Artificial Nuclear Reactions
Thus this phenomenon in which artificial transmutation of a stable non - radioactive nucleus leads to the formation of radioactive isotope is called artificial radioactivity or induced radioactivity. Some of the isotopes produced as a resu..

Radioisotopes find numerous uses in different areas such as medicine, chemistry, biology, archaeology, agriculture, industry and engineerin..
Artificial Nuclear Reactions
Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity..
Uses of Radioactive Isotopes
All isotopes of a substance have the same chemical properties and behave in an identical manner. The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits. It has wide applications in various fields lik..
Applications to some familiar systems
. When a radioactive nucleus (initially at rest) decays, the fragments fly in different directions, obeying the principles of momentum and energy conservation. As the decay occurs spontaneously, no external forces are involved. The momentum of the system is conserved. As the parent nucleu..
Nuclear Chemistry Summary
Nuclear changes can be brought about by bombardment of nuclei with accelerated particles like neutrons, deuterons and protons. A particularly important process for the production of artificial radioactive isotope is the (n, g ) reaction, which is applied to synthesize new ..

..Background Radiation
Background Radiation - In astronomy, the low temperature microwave radiation that arrives at the earth's surface from all directions of outer space is called background radiation. It is so named because it forms a background to all the radio sources that have been detected by radio telescopes. Cosm..
Uses of Sulphur, Selenium and Tellurium
Uses of Sulphur, Selenium and Tellurium - (i) Most of the sulphur produced is used for the manufacture of sulphuric acid and other industrially important sulphur compounds. (ii) Sulphur is used to prepare large number of medicines (Sulpha drugs) and can be used as ointment for curing skin diseases...

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
