Whereas the science underpinning the generation of electricity from nuclear power is well established the health effects on humans of ionising radiation is still evolving. The history of human health and the safety of nuclear power is inexorably intertwined with the evolving history of the health effects of ionising radiation ir. Radionuclides are elements uranium 235 uranium 283 thorium 232 potassium 40 radium 226 carbon 14 etc with unstable atomic nuclei and on decomposition release ionizing radiations in the form of alpha beta and gamma rays.
Geetanjali kaushik aies 2. Somatic affects the. Radiation effects can be somatic or genetic.
Studies shown that the health effects due to radiation are dependent on the level of dose kind of radiation duration of exposure and types of cells irradiated. Uranium mining and milling nuclear reactors and reprocessing of nuclear fuel cause nuclear pollution. Most common type of health hazards that are caused by radiation exposures are.
End point effect is to produce biological damages causing different types of health problems. Radioactive rays are highly energetic and can deposit large amount of energy in human tissues. Nuclear hazards argha deb radioactive health hazards.
The nuclear fuel cycle does not give rise to significant radiation exposure for members of the public and even in two major nuclear accidents three mile island and fukushima exposure to radiation has caused no harm to the public. Nuclear radiation and health effects updated april 2020 natural sources account for most of the radiation we all receive each year. If people come in direct contact with fallout beta burns from shallow ionizing beta.
Thermal burns from infrared heat radiation these would be the most common burn type experienced by personnel. The first and most major cause of burns is due to thermal radiation and not caused by ionizing radiation. In a nuclear explosion the human body can be irradiated by at least three processes.

Nuclear hazards and human health risks. Source effect and control 2. Definition risk or danger to human health or the environment posed by radiation emanating from the atomic nuclei of a given substance or the possibility of an uncontrolled explosion originating from a fusion or fission reaction of atomic nuclei. The greatest exposure to human beings comes from the diagnostic use of x rays radioactive isotopes used as tracers and treatment of cancer and other ailments. Effects of nuclear hazards the effects of radioactive pollutants depend upon half life energy releasing capacity rate of diffusion and rate of deposition of the contaminant.
Ionizing radiation is generated through nuclear reactions and can be very harmful to human health. Nuclear reactions can be naturally occurring or artificial. There are three basic types of radiation. These include alpha beta and gamma radiation.
