What is 137 in nuclear?
Cesium- 137 is a radioactive isotope of caesium which is formed by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. It is among the most problematic of the short-to-medium-lifetime fission products because it easily moves and spreads in nature due to the high water solubility of caesium’s most common chemical compounds, which are salts.

What is a Geiger counter?
Geiger counters are used to detect ionizing radiation. The primary component of the Geiger counter is a tube filled with a gas that conducts electricity when struck by radiation. This allows the gas to complete an electrical circuit. This typically includes moving a needle and making an audible sound.

Radiation Exposure
- It can be hard to predict the impact of radiation on humans but around half of all those exposed to 5 sieverts will die from it. Almost all who receive a dose of 10 sieverts will die within weeks. A typical dose for those workers who died within one month of the disasters was 6 sieverts. During the Chernobyl disaster four hundred times more radioactive material was released than at the at…

The reactor staff struggled to establish the levels of radiation following the explosion as one dosimeter capable of measuring up to 9Sv per second 1,000 R/s was burie…
Levels of Radiation in Pripyat and Chernobyl Now
- The levels of radiation as measured in 2009 (Radiation levels can, and do, fluctuate depending on a number of factors.)
Risk
- Generally the levels of radiation in Pripyat and the surrounding area, although far higher than the norm, are safe for the time you will be exposed to them (just don’t go licking stuff). Those who work within the zone typically work 3 weeks on, 3 weeks off. The “off” period must be spent outside of the zone. Radiation levels can change daily, dependent upon a number of factors incl…
