Question

Among the most dangerous non-biodegradable waste is

• A. cow-dung
• B. plastic articles
• C. garbage
• D. radioactive waste

Answer 1

Answer: (D)

Radioactive waste is most dangerous because it is non-biodegradable and undergoes radioactivity in which the radioactive element emits alpha, beta and gamma particles. Radioactive elements are hazardous and can cause serious health problems like Strontium 90, a dangerous radioactive pollutant can cause cancer and leukaemia. Radioactive wastes are dumped into water bodies and from there, they enter the food chain and accumulate in the body of an organism. Dumping of radioactive wastes should be done very carefully deep in the ground where they will degrade.

So, the correct answer is 'radioactive waste'.
