There is in fact a long list of equipment on the Y2K danger list: One is the cobalt-60 therapy unit used for treating cervical cancer. Because the calculations of the radiation dosage are connected to the half-life of cobalt, a mistake in the date would affect the amount of radiation delivered, giving patients more or less than they need, which would have serious consequences.
在 Y2K 危險名單上的醫療設備還有一長串：治療子宮頸癌的鈷六十放射線治療機，由於其放射線劑量的計算和半衰期有關，日期錯誤將影響到劑量的多寡，導致病人接受的照射量過多或不足而引發嚴重後果。
