write any three features of natural and artificial radio activity?
Answers
Emission of radiation due to self- disintegration of a nucleus.
Emission of radiation due to disintegration of a nucleus through induced process.
2 Alpha, beta and gamma radiations are emitted. Mostly elementary particles such as neutron, positron, etc. are emitted
. 3 It is a spontaneous process.
It is a induced process
4 Exhibited by elements which atomic number more than 83.
Exhibited by elements with atomic number less then 83.
5 This cannot be controlled.
This can be controlled.
mark me as brainliest please :)
please
Three features of natural and artificial radio activity are as follows:
Natural Radio Activity
When the naturally occurring unstable nucleus emits active radiations, then the process is known as Natural Radio-Activity.
Features of Natural Radio-Activity
- Self- Disintegration of the nucleus results in the emission of radiation.
- They emit Alpha, Beta, and Gama radiations
- This is a spontaneous process
Artificial Radio-Activity
When man-made activity is performed to emit active radiations, then the process is known as Artificial Radio-Activity.
Features of Natural Radio-Activity
- The disintegration of the nucleus results in the emission of radiation, but it is man-made.
- They emit neutrons, positrons, etc. radiations.
- This is an induced (man-made) process.
Thus, natural radioactivity is done by itself whereas artificial radioactivity is man-made.
