- Radiation of cosmic origin- Radiation from radioactive elements (and decay products) of the Earth- Internal radiation of organisms
The film badge measures radiation exposure; an exposed film badge indicates how much radiation a worker has recieved.
the source of ultra violet radiation are due to sunlights, cause by the thinning of ozone layer bcause of the chemical reactions cause by the chemicals from the lithosphere
You're referring to what's called background radiation, which is emitted from various isotopes that can be found in many, many different materials.
Some of the elements in your body are naturally radioactive. e.g. potassium, some carbon, etc. You get a larger exposure to radiation from the decay of potassium in your body, than you will from a smoke detector based upon radioactive americium.

Common sources of ionizing radiation are alpha particles, beta particles, ultra-violet light, X-rays and gamma rays. Everybody is exposed to small amounts of these radiations every day just from general background radiation or from sunlight.
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
Petroleum, natural gas, and coal
earths crust, radon gas, cosmic rays, natural sources e.g food, water and rocks.
Russia's main power or energy sources are natural gas, coal, and oil. Russia has the largest reserves of natural gas out of every country in the world.
People exposed to certain pesticides and ionizing radiation have a higher than average chance of developing this disease.
