Oral epidemic diseases of exposure personnel in long-term low-dose radiation yet have rarely been studied.Referred to WHO oral health survey method and symptom grading standard, data of 341 exposure persons in long-term low-dose radiation including α particle, β particle, and γ rays, etc., were collected from one camp in China in 2011 with cluster sampling and analyzed ? with Foxpro 6.0 and SPSS 16.0 software.The exposure persons worked in low-dose radiation for a long time aged between 23 and 56, whose average age were 27.1 years old.In addition, their lengths of service were from 2 to 34 years (average 7.9 years) and average exposure time was 8 hours a day each year for more than three months.Average annual radiation dose equivalent was from 1.8 to 16.5 mSv (average 7.3 mSv).Total radiation dose equivalent was from 3.8 to 425.0 mSv (average 97.3 mSv).
