August 8, a little over a month ago, in the militarya test site in the Arkhangelsk region there was an explosion of a rocket accelerator, which led to an increase in the level of radiation. This caused alarm both in our country and abroad. Subsequently, Roshydromet reported an increase in radiation background by 16 times, but five days after the explosion, residents of the nearest village of Nenoksa were evacuated. This means that most likely another planet infected with radiation has appeared on our planet. Unfortunately, there are much more of them on Earth today than we would like.

How dangerous is radiation?
Despite the fear that exists regardingnuclear power plants, currently in most countries of the world the industry provides safe handling of radioactive sources. In order to make sure that the radiation levels to which plant workers are exposed and the people near them remain safe, it is important to control three variables: distance, radiation protection (shielding) and exposure time.
According to the Spanish Epidemiological Reportthe Foro Nuclear Center, the effects of ionizing radiation on human health are significant when people are exposed to high doses of radiation. However, in the case when the level of radiation exposure is very low, do not worry.
The report includes the findings of several studies onthe health status of residents near radiation-contaminated zones that have been carried out since 1940. Among them, there is no increase in cancer mortality in any of the studied areas except Chernobyl. Unfortunately, experts recorded a significant increase in thyroid cancer among children.
Although in the 21st century the improvement of nuclear safetypower plants minimized the risk of a new nuclear disaster with the same impact as in Chernobyl, nuclear waste and its management remain a serious environmental problem. However, the recent explosion in Severodvinsk once again demonstrates to the whole world that nuclear disasters of all sizes can be repeated. But how many territories on our planet that are unsafe for life due to radiation? Let's get to know some of them.
The worst nuclear disaster in historyof humanity occurred, as you know, at the Chernobyl nuclear power plant. The consequences of the disaster, which infected a territory within a radius of several kilometers, in addition to deaths directly at the scene of the accident, killed more than 4,000 people, causing cancer. To date, the exact number of people affected by the accident is not exactly known.
Today Pripyat is a ghost town thatlocated in the exclusion zone of the vicinity of the Chernobyl nuclear power plant. However, over time, the level of radiation gradually decreases, so today you can visit Pripyat by taking the necessary precautions.
Have you watched the HBO series dedicated to the Chernobyl accident? Let's discuss this in our Telegram chat.
Republic of the Marshall Islands is a Pacificstate of micronesia. Between 1946 and 1958, the United States tested 67 nuclear weapons in the Marshall Islands. Unfortunately, these tests left an imprint that remains in some regions. Scientists conducted a study according to the results of which they do not recommend settling some of the islands, as this can be a health hazard. The islands on which radiation pollution exceeds Chernobyl are Enjebi, Runit, Bikini and Nayen.
One of the worst nuclear disasters inthe world was the 2011 earthquake in Japan, which caused a tsunami that swept the coast and affected the Fukushima-1 nuclear power plant. Japan is one of the countries with the highest seismic activity in the world. So we should definitely think about where to build nuclear power plants.
The natural disaster that caused the accident is notcaused human casualties, but the vast territory is no longer suitable for life. The energy released during the earthquake was equivalent to the explosion of 200 million tons of dynamite. In addition, the level of radiation in food products after the accident exceeded the established legal maximum by 27 times. Fortunately, the radioactivity in this area is gradually disappearing.
Mayak Station, Russia
Unfortunately, Chernobyl is not the only nucleardisaster in the USSR. For many years, the Soviet authorities tried to hide several radioactive emissions produced at the Mayak NPP. In particular, the releases of radioactive waste on the Techa River in 1957, the explosion of the building where this waste was stored. This made the area near Mayak station one of the most radioactive places on the planet. After Chernobyl and Fukushima, it is considered the third most serious nuclear accident and has a level of 6 on the INES scale (International Nuclear Event Scale).

Hanford Complex, United States
Millions of tons of nuclear waste have been stored inHandford, USA, from 1943 to 1945. This place is located on a plain in the center of Washington, where the exhaustive process of cleaning the territory from radiation pollution is still undergoing. This area can only be considered safe after several decades.
