Different amounts of radiations exist as part of the natural environment

Over the past few years, multiple concerns have been raised about the safety standards of functioning nuclear facilities, in terms of emissions or potential accidents, such as those at Chernobyl and Three Mile Island. Protesters have significantly increased their activities throughout the world, and especially in the United Kingdom, where nuclear plants are constantly boycotted. But very few people are aware of the radiation levels that already exist in the atmosphere due to natural processes and their potential consequences.  

Radionuclides are small radioactive particles that can originate from habitats where no human activity is present. They have multiple sources, including volcanoes and uranium deposits in their natural state. However, a large part of these particles come from human activities, such as cover mining, electricity generation, waste disposal, air pollution and phosphate fertilizers. Radioecologists worldwide have begun cooperating towards developing efficient means of tracking down these particles and preventing them from reaching food or water supplies and livestock.

  To this end, the 4th International Symposium on Nuclear Metrology as a Tool for Radioecology is being held in Morocco this week. The gathering is hosted by the country's National Centre for Energy, Sciences and Nuclear Techniques (CNESTEN) and it is attended by some of the most prominent specialists in the field. The International Atomic Energy Agency (IAEA), along with several other similar, regional and nation institutions, has offered its full support and cooperation in the matter.  

Reports about human activities that could increase the numbers of radionuclides currently present in the atmosphere are coming in from literally all around the world – the U.S., the Middle East, Europe and Central America. "Naturally occurring radioactive materials," which cannot be subjected to human regulations or limitations, are also discussed this week, in the hope that scientists could find a way to better understand the mechanisms through which they are generated and how to control them.

 

The next few years could see the development of solid infrastructure bases throughout the world, meant to monitor and offer real-time warning against the dangers posed by radiation levels in all regions of the globe.
