All the studied radiological parameters were higher than the recommended limit by the IAEA in all ash samples. A good starting point to look for radiological hazards is to start with getting information or analysing your potable water source (well or municipal) or a regular basis. Radiological hazards may originate from a nuclear facility-due to accidental release or damage created by a natural disaster. Next to this asking information from the authorities on the composition of the soil around your plant and / or the fields you use to grow crops is also a wise thing to do. The radiological assessment of accident victims, bystanders, patients and response personnel operating in contaminated areas requires definitive results.

The FDA "Hazard Analysis and Risk-based Preventive Controls for Human Food" regulation, referred to as Preventive Controls for Human Food (PCHF), defines "Hazard" as "any biological, chemical (including radiological), or physical agent that has the potential to cause illness or injury." The parenthetical in that definition is a new descriptor to those who have conducted… The study area is a gold mining area situated about 70 km west of Johannesburg in the province of Gauteng in South Africa. Depending upon the activity concentration of primordial radioactive elements, various radiological hazards delivered to the surrounding living biota can be assessed. In many cases, the risk of a hazard is expressed as a combination of frequency and severity [7-8]. It is suggested that a given dose of radiation carries a risk of leukemia but that the risk is greater in old than young subjects. An assessment of a radiological risk arising from using such products in the painting of living areas is conducted when Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) was observed, with a daily inhalation exposure dose being of particular concern.

It is possible that elevated radiation levels may occur many miles from the site of a nuclear detonation and pose the risk of radiation exposure from environmental, victims (including fatalities and survivors), and equipment contamination. With the implementation of the Food Safety Modernization Act (FSMA) in the USA, a lot of food producers , also internationally, have to assess the risks they face of radiological hazards as part of their HACCP approach. For water, your control here would be that you use the reports produced by your local authority, to make sure that the local water supply is not contaminated. , which is the radium equivalent activity, is the most widely used radiation hazard index [34, 35]. The safety assessment in site selection for a new nuclear power plant is an essential issue for human health. Unlike some other types of energy, such as heat (infrared radiation) or visible light, the human body cannot sense exposure to ionizing radiation. Assessment of baseline knowledge of radiation hazards and radiation protection practices of special groups at risk is essential in designing appropriate strategies for the prevention of unnecessary exposure to ionizing radiation not only among health workers but their patients also. Monitoring of radiological parameters in oil and gas industry is essential to maintain the radiation levels within safe limits. Being prepared for an emergency is the best insurance that it won't happen. hazard analysis. Identify biological hazards -determine whether workers may be exposed to sources of .
