Cyanobacteria also known as one of the first organism on earth are responsible for producing nearly 80% of the oxygen on earth.
Since the radiation has no mass .It is Gamma radiation.
Step by Step Explanation:
Characteristics of Gamma radiation are as follows:
- Gamma radiations are chargeless.
- It is Electromagnetic wave having a very short wavelength.
- It is not effected by the electric or magnetic field.
- It has velocity equal to light in vaccum .
- It has a very high intensity and can penetrate long distances.
- It has a very low ionizing power. i.e. it does not ionize the medium in whic it travels.
Gamma radiation has proved itself to be very useful in radioactive treatment of cancer due to its high penetrating power.
