The world’s nuclear powers (cường quốc hạt nhân) have detonated (làm nổ, kích nổ) more than 500 nukes in the atmosphere. These explosions (vụ nổ) were tests (thử nghiệm), shows of force (thể hiện sức mạnh) to rival nations (nước địch thủ), and proof that countries such as Russia, France, and the U.S. had mastered the science of the bomb. The world’s honey (mật ong) has suffered for it. According to a new study published in Nature Communications, honey in the United States is full of fallout (phóng xạ nguyên tử, bụi phóng xạ) lingering (nán lại, chần chừ, sống lây lất) from those atmospheric nuclear tests.

For the study, researchers collected honey samples from more than 100 hives and soil samples from 110 locations across the Eastern United States. The scientists found elevated levels of cesium in both the soil and honey samples. “While most of the radiation produced by a nuclear weapon detonation decays within the first few days, one of the longest-lived and more abundant fission products is [cesium] , which has a radioactive half-life of 30.2 years,” the study said.

Previous research after the Chernobyl nuclear disaster identified elevated levels of cesium in European honey and pollen. The good news is that, according to researchers, most of this honey is probably safe for humans to consume.
