INTRODUCTIONThe world's worst nuclear accident occurred on April 26, 1986. The states of Belarus, the Russian Federation and Ukraine were subjected to numerous studies on the health effects of radiation from The Chernobyl accident have been conducted for the past 25 years. The main purpose of this report is to analyze the health effects of invisible radiation. Studies have shown important links between radiation and cancer, particularly in relation to the risk of thyroid cancers resulting from exposure to high-level radiation. The issues to be discussed will be to analyze risk management and safety in order to prevent another Chernobyl disaster and to reveal why the world really came to know the name “Chernobyl”. Severe radiation exposure is incurable and excruciating, and mainly affects cancer and non-cancerous effects. BODY Radioactivity refers to the spontaneous emission of a stream of electromagnetic rays in nuclear decay. The effect of a high dose of radioactivity is dangerous, the blood count changes and within a few hours or days the immune system is deactivated and infections begin to appear. The gastrointestinal tract is affected and the person is forced to vomit, other internal organs such as the central nervous system (CNS) are also damaged. Any dose of radiation, no matter how small, can cause cancer; the question is: how often does this occur if other diseases can also be attributed to it. According to new studies, the effects of low-level radiation include genome instability, DNA mutations, malformations and increased cellular aging. The radioactive elements dispersed from Chernobyl are the isotope iodine 131 which has a half-life of eight days and is stored in the atmosphere. thyroid gland causing thyroid cancer. Cesium 137 is a... middle of paper......rats and other cardiovascular diseases regarding low doses and low radiation dose rates. Studies conducted on Chernobyl liquidators have provided sufficient evidence of the increased risk of cardiovascular disease and other cancerous diseases. Works Cited1.
