[17] [18] The initial evidence that a release of radioactive material had occurred came not from Soviet sources, but from Sweden, where on 28 April, [19] two days after the disaster itself, workers at the Forsmark Nuclear Power Plant, approximately 1100 km from the Chernobyl site were found to have radioactive particles on their clothing.
On April 26, 1986, Chernobyl’s reactor number four melted down as a result of human error, releasing vast quantities of radioactive particles and Military action in radioactive Chernobyl could ...
[8] All of these elements only deteriorate through radioactive decay, which is also known as a half-life. [3] Half-lives of the nuclides previously discussed can range from mere hours, to decades. [3] The shortest half-life for the previous elements is Zr 95, an isotope of zirconium which takes 1.4 hours to decay. [3]
The four most harmful radionuclides spread from Chernobyl were iodine-131, caesium-134, caesium-137 and strontium-90, with half-lives of 8 days, 2.07 years, 30.2 years and 28.8 years respectively.

During the aftermath of the reactor core fire, a vast amount of airborne radioactive contamination was released into the open air. The Soviet military responded by deploying a large fleet of Mil Mi-8 helicopters, which were tasked with dropping radiation-absorbing materials—composed of boron carbide, clay, dolomite, lead, and sand—onto the blazing reactor.
