14) How Could People Be Living in Nagasaki and Hirshima?
I asked copilot and the answers are contradictory. I still don't understand. You How could anybody be living in Nagasaki and Hiroshima when the half lives of radio isotopes is often in the hundreds of years? Copilot After the atomic bombings of Hiroshima and Nagasaki in 1945, the release of radiation and toxic pollutants was indeed significant. However, the situation has evolved over time, allowing people to live safely in these cities. Let’s explore why: Short Half-Lives of Radioisotopes: Many of the isotopes emitted during the atomic bomb explosions have short half-lives. For instance, isotopes like Niobium-95, Barium-140, and Iodine-131 decay relatively quickly. A half-life refers to the time it takes for half of a given quantity of a radioactive substance to decay. Isotopes with short half-lives decay rapidly, and after several days, effectively nothing remains of them1. As a result, the intense radioactivity at the bomb sites diminished rapidly after the initial explosions2. ...
