Why Hiroshima and Nagasaki are safe to live in today

The article discusses the current safety of Hiroshima and Nagasaki, the cities that were devastated by the atomic bombings in 1945. According to the BBC science reporter Esme Stallard, the radiation from these events is now undetectable. The article explains that the radiation levels in Hiroshima and Nagasaki have declined significantly over the past 75 years. This is due to the short half-life of the radioactive isotopes released during the bombings, which have since decayed. Today, the radiation levels in these cities are no different from those found in other parts of the world. The article highlights that the cities have been extensively studied, and the data shows that the long-term health effects of the bombings, such as increased cancer rates, are not significantly different from the general population. This suggests that Hiroshima and Nagasaki are now safe for people to live in, with no elevated radiation risks.
