Wastes may be sealed in concrete- filled drums and discharged to a depth of about 500 m. This specific statement is true for a. Solid waste pollutants b. U.V. radiation pollutants c. Particle pollutants d. Radioactive pollutants
Radiation pollutants are the waste materials that release non ionizing radiation. UV radiation can be easily blocked by proper clothing and applying sunscreen. Hence UV pollutants don't need such a strong sealing. Particle pollutants are present everywhere in the atmosphere and hence can't be sealed. Most of them are not harmful to humans. Radioactive pollutants are the waste materials that release ionizing radiation which can be very dangerous to human beings. hence this kind of waste may be sealed and concrete filled drums and discharged to a depth of 500 m. So the correct answer is ' Radioactive pollutants'.
