Detailed explanation-1: -An increased incidence of thyroid cancer was observed for about 4 years after the accident and slowed in 2005. The increase in incidence of thyroid cancer happened amongst individuals who were adolescents and young children living during the time of the accident, and residing in the most contaminated areas.
Detailed explanation-2: -Aquatic bodies are still being contaminated by runoff of long lived caesium-137 and strontium-90 released from contaminated soils. At present, the water and fish of rivers, open lakes and reservoirs have low levels of caesium-137 and strontium-90.
Detailed explanation-3: -The Chernobyl disaster caused serious radiation sickness and contamination. Between 50 and 185 million curies of radionuclides escaped into the atmosphere. Millions of acres of forest and farmland were contaminated, livestock was born deformed, and humans suffered long-term negative health effects.
Detailed explanation-4: -The accident at the Chernobyl nuclear power plant in 1986 released radioactive substances – including iodine, caesium, strontium, and plutonium – into the atmosphere. In Central Europe, only caesium-137 is relevant for the radiation to which humans and the environment are still exposed.
Detailed explanation-5: -Increased risk of thyroid cancer has been one of the most important adverse health effects observed after the accident. The energy from ionizing radiation breaks the chemical bonds in DNA, resulting in a number of different types of damage.
