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. （點(diǎn)擊《每日郵報(bào)》查看原文）
牙科X光恐引發(fā)腦瘤
???????據(jù)英國《每日郵報(bào)》報(bào)道，每年有數(shù)百萬英國人照牙科X光片，而這可能會(huì)增加罹患腦瘤的機(jī)率。
???????一項(xiàng)大規(guī)模的研究發(fā)現(xiàn)， 經(jīng)常照射牙科X光片能讓男女病人罹患一種腦瘤，而這種機(jī)會(huì)是普通人的2倍。這種腫瘤會(huì)影響到人們的性格、視力、說話能力，甚至讓身體一側(cè)癱瘓。
???????而經(jīng)常照牙齒X光的人群中，兒童最易受到影響。10歲以下兒童經(jīng)常受低劑量的輻射，會(huì)使他們得腫瘤的風(fēng)險(xiǎn)增加5倍。
