Radiation levels in Fukushima are less than Expected

Residual radiation from Japan’s 2011 Fukushima Daiichi nuclear plant are less than expected. A study was conducted and published, following radiation levels in tens of thousands of residents living near the site of the accident. The study was published in the Journal of Radiological Protection in December.

Nuclear accidents have disastrous effects on human health as well as the surrounding environment. Radiation exposure on individuals have dangerous side effects and keeping track of and treating these individuals is difficult and costly. Radiation levels are measured on each individual that has been exposed.

The tsunami and earthquake that damaged the Fukushima plant had sent radioactive material pouring out into the open. The government had formed estimates based on aircraft surveys. Officials nearby at the city of Date handed out “dosimeters” or radiation tracking devices to the city’s residents. The government argues that people were spending most of the day inside buildings that shielded them from radiation exposure.

The study’s conclusion stated the “method obtained in this study could aid in the prediction or in the estimation of the external doses of residents in the early phase of future radiation accidents involving large-scale contamination.”
