it is generated by radioactive atoms and in nuclear explosions?​

Sagot :

Answer:

It is generated by radioactive atoms and in nuclear explosions produce some radioactivity in our surrounding too, create natural background radiation, but most of it only go straight to the ground and become absorbed. In a city, the radioactivity is going everywhere, even if it does slowly decay and it becomes undetectable in a town, it is only a matter of days and will be alright if you run the right tests. Natural background radiation is normal in our environment because we share our planet with other solar systems and it's effect on us is visible on people born before 1970, otherwise normal human population is immune to it, live normal lives and not aware of any risk.
