Wind direction and topography, such as mountains, play an important role in dispersal of radioactive materials. Nuclear reactors legally leak lethal radionuclides all of the time – it doesn’t take an accident. The authors of the recent study below suggest that higher levels of tritium at 22 km distance from a nuclear power station, in contrast to 10 km distance, is due to either dominant wind direction, or a protective effect of a mountain between the reactors and the 10 km location, or a combination of the two.

Shanghai is located to the northeast of these nuclear reactors.

When measuring radiation, the ability of radioactive materials to travel long distances and the importance of wind direction and topography are important things to consider. If measurements are consistently higher when the wind blows from a certain direction, it is worth checking what is in that direction – even if a long distance away.
