Radiation on Health
Radiation on Health: Talks between the United States and Iran have failed. This raises fears of nuclear threats. In the last century, DNA-related diseases have increased. Experts link this rise to radiation and pollution.
Radiation History
Atomic radiation became a major danger after the bombings of Hiroshima and Nagasaki in 1945. After World War II, countries built more nuclear weapons. They also launched satellites. These actions increased radiation in the environment. Several radiation leaks also occurred. Major cases include the Chernobyl disaster and the Fukushima Daiichi nuclear disaster.
Radiation Damage
Radioactive materials release energy on their own. This process creates ionizing radiation. This radiation harms living tissue. It damages the body in many ways. Common types include alpha particles, beta particles, gamma rays, and X-rays.
Low doses may not show clear effects. Higher doses cause serious harm. Moderate exposure leads to nausea, vomiting, and headaches. It also reduces white blood cells. Higher doses cause hair loss and damage organs. Very high doses can kill within days or weeks.
Immune System Damage
Radiation weakens the immune system. The body cannot fight infections well. It also reduces platelets in the blood. This increases the risk of bleeding. Cuts take longer to heal.
High radiation levels can kill many people. Even low doses can damage DNA. DNA is very sensitive. Damage to DNA leads to serious diseases.
DNA and Cancer Risk
Radiation can change DNA. These changes cause diseases like high blood pressure, diabetes, and thyroid problems. These diseases can pass to future generations. Many people now suffer from them.
Radiation can also cause cancer. It disrupts normal cell growth. Some cells grow out of control. They form tumors. Even low radiation can have long-term effects. These facts show the danger clearly. A nuclear conflict would harm life on Earth.
