Question

Nuclear explosion tests are dangerous because

• A. Radionuclides are released in the atmosphere which spread over long distances by wind
• B. Radionuclides enter the food chain via soil and water
• C. Radiation leakage from nuclear reactors leads to increased radioactivity in the environment
• D. All of these

Answer 1

The correct option is D All of these

Nuclear explosion tests are a major cause of radiation pollution. During atmospheric nuclear explosion tests, a number of long-lived radionuclides are released into the atmosphere and are then dispersed over long distances by winds from the test site. These radionuclides often settle down by rain and get mixed with soil and water, easily enter the food chain and finally get deposited in the human body where they cause serious health hazards. Radiations may leak from nuclear reactors and other nuclear facilities that could result in the release of radioactive materials which raise the level of ionising radiations.
