Dental X-rays, given to millions of Britons each year, may raise their odds of developing a brain tumor, the Daily Mail reported.
A large-scale study found that men and women with the type of tumor that can affect personality, sight, speech and even paralyze one side of the body, were twice as likely to have had the most common form of dental X-ray than those who were free of the disease.
With another type of tooth X-ray, children appeared to be most vulnerable, putting those regularly exposed to the low-dose radiation while under the age of ten, at almost five times greater risk. (点击《每日邮报》查看原文)
牙科X光恐引发脑瘤
据英国《每日邮报》报道,每年有数百万英国人照牙科X光片,而这可能会增加罹患脑瘤的机率。
一项大规模的研究发现, 经常照射牙科X光片能让男女病人罹患一种脑瘤,而这种机会是普通人的2倍。这种肿瘤会影响到人们的性格、视力、说话能力,甚至让身体一侧瘫痪。
而经常照牙齿X光的人群中,儿童最易受到影响。10岁以下儿童经常受低剂量的辐射,会使他们得肿瘤的风险增加5倍。
