Abstract The Fukushima-Daiichi Nuclear Power Plant (FNPP) accident in March of 2011 released substantial amounts radionuclides into the environment. We collected 4,957 deciduous teeth formed children before Fukushima to obtain precise control data for after accident. Radioactivity was measured using imaging plates (IP) and epidemiologically assessed multivariate regression analysis. Additionall...

In-situ and ex-situ measurements of environmental radioactivity were made on the iThemba LABS (iTL) grounds in South Africa. The MEDUSA and HPGe detector systems were used to make insitu and ex-situ measurements, respectively. The MEDUSA was mounted ∼0.5m above the ground on a 4× 4 vehicle to traverse [at ∼2m · s−1] the accessible portions of the iTL grounds. Spatial data (via a GPS receiver) w...
