RADON SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Radon
Radon, Rn simgesi ve atom numarası 86 olan bir kimyasal elementtir. Radyoaktif, renksiz, kokusuz, tatsız soygazdır ve doğal olarak uranyum veya toryumun dolaylı bir bozunum ürünüdür. En kararlı izotopu 222Rn'nin yarı ömrü 3.8 gündür. Radon, normal koşullar altında gaz kalmış en yoğun maddelerden biridir. Normal koşullar altında yalnızca radyoaktif izotoplara sahip olan ve radyoaktivitesi nedeniyle sağlık açısından tehlike olarak kabul edilen tek gazdır. Yoğun radyoaktiflik radonun kimyasal çalışmalarını engelledi ve sadece birkaç bileşik biliniyor. Radon, normal radyoaktif bozunma zincirlerinde bir ara adım olarak oluşur; bu zincirler aracılığıyla, toryum ve uranyum yavaş yavaş kurşuna dönüşür. Toprakta iki en yaygın radyoaktif element olan toryum ve uranyum; yeryüzünün oluşmasından bu yana etrafındalar. Onların doğal olarak oluşan izotopları, milyarlarca yıl boyunca çok uzun yarılanma ömrüne sahiptir. Dolayısıyla toryum ve uranyum, çürüme ürününün radyumu ve bozunum ürünü radon bu nedenle on milyonlarca yılda yaptıkları gibi hemen hemen aynı konsantrasyonlarda ortaya çıkmaya devam edecektir.
İngilizce sözlükte radon sözcüğünün tanımı
Sözlükteki radonun tanımı, nadir gaz grubunun renksiz bir radyoaktif elementidir ve en istikrarlı izotopu radon-222 radyumun bozunum ürünüdür. Radyoterapide alfa parçacığı kaynağı olarak kullanılır. Sembol: Rn; atom numarası: 86; 222Rn yarı ömrü: 3.82 gün; değerlik: 0; yoğunluk: 9.73 kg / m³; Erime noktası: -71 ° C; Kaynama noktası: -61.7 ° C.
