Geiger counters are being used to monitor the nuclear radiations at the Fukushima Daiichi power plant in Japan. A Geiger counter is a radiation detection and monitoring device which records the level of ionizing radiation such as nuclear emission, gamma rays and beta particles. Several websites are displaying results from Geiger counters in the form of graphs which are updated periodically. The demand for Geiger counters has increased drastically in the aftermath of the nuclear radiation exposure risk caused by the Japan Earthquake and Tsunami.


Japan Earthquake and Tsunami resulted in massive damage and nuclear radiation crisis. On March 11, 2011, an earthquake measuring 8.9/9.0 on Richter scale struck the Pacific Ocean near Japan. According to official figures, more than 10,000 people have died or are missing. Another Earthquake with a magnitude of 6.0 hit Japan on Tuesday night, that is, March 15, 2011. Due to the Japan Earthquake and Tsunami, there have been explosions and fires at the six reactors of the Fukushima Daiichi nuclear power plant. The blasts were caused after the cooling systems were damaged. The Fukushima Daiichi nuclear power plant is operated by Tokyo Electric Power Co. The plant was not operational at the time of the Earthquake due to maintenance work, but the spent nuclear fuel rods have caused the risk of nuclear radiation exposure.

According to reports from the nuclear safety agency of Japan, nuclear radiations in the form of steam may have escaped from the Fukushima Daiichi power plant after an explosion badly affected the suppression chamber of reactor two. There is high risk of nuclear radiation exposure as radiation dosages of up to 400 millisieverts per hour were registered at the power plant.
