Radionuclides are elements uranium , uranium , thorium , potassium 40, radium , carbon 14 etc with unstable atomic nuclei and on decomposition release ionizing radiations in the form of alpha, beta and gamma rays. Out of the known 45O radioisotopes only some are of environmental concern like strontium 90, tritium, plutonium , argon 41, cobalt 60, cesium , iodine , krypton 85 etc.

The environmental impact of nuclear power results from the nuclear fuel cycle , operation, and the effects of nuclear accidents. The greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal, oil and gas, and the routine health risks are much smaller than those associated with coal. However, there is a "catastrophic risk" potential if containment fails,  which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the environment.
Metrics details. The safety assessment in site selection for a new nuclear power plant is an essential issue for human health. It could be improved by predicting the consequences for a hypothetical accident. This paper is contextual with the nuclear safety regarding the risk upon human health from the hazard constituted by the emission of radioactive material due to a hypothetical nuclear power plant accident.

The fission products produced during normal operation of nuclear plant, remain with in the fuel elements and also in the nuclear wastes. Contamination can also place due to coolant leak and causes emission of radioactive gases.
White blood cell count drops. Severe radiation sickness 3. One Roentgen is defined as the quantity of radiation which produces 1. Very high doses of radiation may totally destroy cells, causing immediate death. Cells with damaged DNA may begin dividing and growing out of central forming malignant tumours and leukaemia disease in which too many white blood cells are produced causing finally death.
All the above health hazards and adverse effects are directly related to the level of exposure. Generally, the doses in the range of 10 — 15 rem result in the increased risk of cancer. Radiation resistant enclosures or barriers are to be placed for screening workers from radioactive materials Chernobyl Where is the Chernobyl Plant?

Essay on Nuclear Pollution: Sources, Effects and Control
Ionizing radiation Ionizing radiation Radiation with so much energy it can knock electrons out of atoms. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. Fortunately, the cells in our bodies are extremely efficient at repairing this damage. However, if the damage is not repaired correctly, a cell may die or eventually become cancerous. It can also result in long-term health effects such as cancer and cardiovascular disease.
Assessment of potential human health and environmental impacts of a nuclear power plant NPP based on atmospheric dispersion modeling. Received December 15, ; accepted October 13, The code has produced values of the scaling factors for ground level air concentrations and depositions of radionuclides from the passing plume over our areas of interest. The scaling factors have been used to assess the potential radiological impact on the offsite human and non-human biota. While the radiological impacts on humans were calculated using the popular computation methods set by regulatory authorities, an integrated approach to the assessment and management of environmental risks from ionizing radiation D-ERICA was adopted for the non-human biota.
Radiation plays a key role in modern life, be it the use of nuclear medicine, space exploration or electricity generation. As a result of many decades of research, the health impacts of radiation are very well-understood. The sources of radiation causing the greatest exposure of the general public are not necessarily those that attract the most attention. At its most fundamental level, radioactivity is a question of energy, and the desire for unstable elements to become stable. By releasing radiation, elements go from one energy state to another which, eventually, will result in an element no longer being radioactive. There is a distinction to be drawn between radioactivity on the one hand, and radioactive elements on the other.
Nuclear hazards 1.
