Abstract:
Objective:To investigate the individual irridiateddose levelandhealth statusofoccupational externalexposureamong radiationworkers inThreeA hospitals ofZhejiangprovince,andprovideevidence for occupationalhealthmanagement.
Methods:367 different typesof radiationworkerswereexperienced thedose monitoring and health examination from January toDecember, 2015, according to the requirements of"SpecificationsofIndividualMonitoring forOccupationalExternalExposure"and"Specifications forOccupational healthsurveillance forradiationworkers".The resultsofdosemonitoring,chromosomeaberration rate, lensopacity rate,hemogramand thyroid functionwerestatisticallyanalyzed.
Results:Theannualeffectivedoseamong radiation workers fromZhejiangprovince in2015was0.13mSv,98.91%of them less than1mSv,whichunder the limit standardofstate(20mSv/a).Thechromosomeaberration(dicentric)detection rateswere7.41%and4.35%, from nuclearmedicinegroupand interventionalgroup respectively,whichhigher thandiagnostic radiologygroup, the differencewasstatisticallysignificant(χ2=13.686,8.092,P<0.01).Besides,1caseofsuspiciouschronic radiation dermatitiswas found in the interventiongroup.Radiation lengthhadsignificanteffecton lensopacity rate(P<0.01), lensopacity increasedwith the increasing lengthof the linear trend (χ2trend=16.363,P<0.01),and the incidence ofabnormalthyroid function theabnormalrateof lymphocyte ratiohad significantdifferenceamong theagegroups (P<0.05).
Conclusion:Although, theoccupationalexternalexposureamong radiationworkersinThreeAhospitals ofZhejiangprovince issafe, long-term lowdosesofionizing radiation stillhascertainhealtheffectson the fieldof nuclearmedicineand interventionalradiologystaff,suchaseye lens,cytogenetics,nailsandskin.
