Chernobyl disaster that were contributing factors that led to the incident. These contributing factors include: Both views were heavily lobbied by different groups, including the reactor's designers, power plant personnel, and the Soviet and Ukrainian governments. According to the IAEA's 1986 analysis, the main cause of the accident was the operators' actions. But according to the IAEA's 1993 revised analysis the main cause was the reactor's design. One reason there were such contradictory viewpoints and so much debate about the causes of the Chernobyl accident was that the primary data covering the disaster, as registered by the instruments and sensors, were not
Effects of the Chernobyl disaster the environment although these conclusions have been challenged. Various birds in the area appear to have adapted to lower levels of radiation by producing more antioxidants, such as glutathione, to help mitigate the oxidative stress. Invertebrate populations (including bumblebees, butterflies, grasshoppers, dragonflies, and spiders) significantly decreased. As of 2009, most radioactivity around Chernobyl was located in the top layer of soil, where many invertebrates live or lay their eggs. The reduced abundance of invertebrates could have negative implications for the entire ecosystem surrounding Chernobyl. Radionuclides migrate through either soil diffusion or transportation within the soil solution. The effects of ionizing
