Radiation can indeed affect future generations genetically by causing changes in the DNA of reproductive cells, which can then be passed down to offspring. When living organisms are exposed to ionizing radiation—such as gamma rays, X-rays, or radioactive particles—the energy…
Chernobyl and Fukushima survivors continue to be studied extensively because their experiences provide critical insights into the long-term health, environmental, and social effects of nuclear disasters. These two events are among the most severe nuclear accidents in history, involving large-scale…
Some survivors develop cancer decades later primarily due to the long-term effects of their initial cancer treatments, genetic predispositions, and environmental or lifestyle factors that interact with their altered biology after treatment. Cancer treatments such as chemotherapy and radiation, while…
Radiation poisoning, also known as acute radiation syndrome (ARS), occurs when a person is exposed to a high dose of ionizing radiation in a short period. This exposure damages cells and tissues, especially those that divide rapidly, such as bone…
High doses of radiation cause acute radiation syndrome (ARS) because they inflict severe and rapid damage to the body’s cells and tissues, overwhelming the body’s ability to repair itself and maintain vital functions. When the body is exposed to a…
A radiation dose considered lethal is generally one that causes death in about 50% of exposed individuals within a defined period, often 30 to 60 days. This threshold is known as the LD50 (lethal dose for 50% of people). For…
Radiation burns look different from thermal burns primarily because of the distinct ways in which radiation and heat damage the skin and underlying tissues. While both types of burns cause injury and inflammation, their appearance, progression, and underlying tissue effects…
Radiation can cause damage to the body’s cells, primarily by harming their DNA, which is the genetic material that controls how cells grow and divide. When radiation hits a cell, it can break or alter the DNA strands. This damage…
Radiation causes people to vomit primarily because it damages the cells lining the gastrointestinal tract and triggers a complex biological response involving the nervous system. When a person is exposed to significant levels of ionizing radiation, especially in acute radiation…
Bone marrow failure is a hallmark of radiation poisoning because bone marrow cells are among the most sensitive to radiation damage, and their destruction disrupts the body’s ability to produce essential blood cells. Radiation poisoning, or acute radiation syndrome (ARS),…
