The bombing of Hiroshima was far more dangerous than we thought

The Hiroshima bombing was an effective yet devastating end to the Japanese invasion of World War II, and recent research shows how many victims of this "cruel bomb" [19659004] Research into the radiation effects of the Hiroshima bombing is still on the horizon for a long time, and the project was first begun in the 1970s. According to Sergio Mascarenhas of the University of Sao Paulo, the X-ray and gamma rays of the Hiroshima bombardment have made bones "weekly magnetic" – a phenomenon called paramagnetism.

As early as the 1970s, Mascaren obtained a jawbone from a bomb victim in Hiroshima and tried to find out how much radiation the bones had absorbed. This latest study has also sampled the same jaw, but our research methods have come a long way since the 1970s, with tools such as electronic spin resonance spectroscopy that give us a better understanding of the effects of radiation on these unfortunate victims. To get an idea of ​​the size of the damage, the samples were returned to the original level of radiation that the bone would have experienced when the atomic bomb was dropped.

Oswaldo Baffa, co – author of the study and a Englisch: bio-pro.de/en/region/stern/magazine/…3/index.html Professor at the University of Sao Paulo said: "We have then constructed a curve and extrapolated from it the initial dose when the signal was probably zero, this calibration method allowed us to measure different samples, since each bone and each part of the same bone has a different sensitivity to radiation, depending on its composition. " 19659004] The effects of the bombing of Hiroshima were devastating, but we do not have them. I have a clue how devastating this new study is that revealed that the human jawbone has experienced 9.46 grayscale radiation. Given that it takes only 5 shades of gray to kill a human, it is clear that the damage of the Hiroshima bombing went far beyond the initial explosion – many people due to radiation poisoning in the following days and weeks.

"We used a well-known technique as electron spin resonance spectroscopy to perform retrospective dosimetry, and there is currently renewed interest in this type of methodology due to the threat of terrorist attacks in countries like the United States … Imagine someone planting in New York an ordinary bomb containing a small amount of radioactive material attached to the explosive, and techniques like these can help identify who has been exposed to radioactive fallout and needs to be treated, "Baffa said.

With tools like electron spin resonance spectroscopy, law enforcement officials and health professionals may be better equipped to respond to terrorist attacks and save lives – perhaps reduce the impact of a radioactive attack by responding quickly to target those affected before it's too late , While the likelihood of people experiencing the same devastating attack as we saw in the Hiroshima bombings is quite low, applying this technology to the bomber victims' bones is reassuring as it gives us tools, similar situations in the future tackle. While many people were burned in the first explosion of the Hiroshima bombing, there were many more who soon after disappeared from the nauseating effects of the radiation. The fact that the radiation exposure was almost twice as high as the lethal dose of a person brings home the incredible damage that an atomic bomb brings.

The results of this study are titled "Electron Spin Resonance (ESR) Dosage Measurement in the Bones of Hiroshima A Bomb Victims" and were first published in the journal PLOS One.
