尋找加州紅酒中福島銫-137的痕跡 Fukushima’s nuclear signature found in California wine



Ítalo Silva “But the team was able to carry out more-sensitive tests by opening the wine and reducing it to ash by evaporation. This involves heating the wine to 100 degrees Celsius for one hour and then increasing the temperature to 500 degrees Celsius for eight hours. In this way, a standard 750-milliliter bottle of wine produces around four grams of ashes. The ashes were then placed in a gamma ray detector to look for signs of cesium-137.” That’s exactly how I drink my wine...
ÍtaloSilva“但該團隊能夠通過打開葡萄酒瓶,並通過蒸發將其減少為灰分來進行更敏感的測試。 這包括將葡萄酒加熱至100攝氏度1小時,然後將溫度升至500攝氏度8小時。 通過這種方式,標準的750毫升葡萄酒瓶可產生約4克的灰燼。 然後將灰燼放入伽馬射線探測器中,尋找銫-137的痕跡。“這正是我喝酒的方式......


These results show nuclear disasters can have unexpected consequences long after the fact.
