Key Points:

  • Nuclear radiation causes severe damage to the human body at the molecular level by ionizing cells, leading to DNA breaks, protein deformation, and cell malfunction, with rapidly dividing cells like those in children being most vulnerable.
  • Radioactive particles can settle in organs such as lungs, bones, and thyroid, continuing to irradiate the body for extended periods and increasing the risk of long-term health issues like cancer.
  • High doses of radiation can cause acute radiation poisoning with symptoms like nausea, confusion, and collapse, while prolonged low-level exposure may contribute to cancer development, prompting efforts to reduce radiation exposure in medical procedures.
  • Nuclear disasters like Chernobyl and Fukushima have provided critical insights into radiation's unpredictable environmental spread and its devastating effects on human health, leading
