PEN Dosimeter Instruction ManualThe PENS are rugged direct-reading carbon fiber dosimeters that measure anddirectly display the radiation dose or quantity of gamma and x-ray exposure.Procedure For Dose Measurement UsingPEN DosimetersLens1)Look through lens of dosimeter towardsa bright light.2)Fiber should be at zero.If it is not,recordmeasurement,or use Radiation AlertCharger to charge dosimeter beforeusing.3)Once fiber is on zero,clip dosimeter toDosimeterperson or object to be monitored.4)Record time and date.View of PEN200 scale through lens5)When monitoring is complete,recordtime,date,and dosimeter measurement.MILLIROENTGENSS'nTo obtain dosimeter measurement;050100150200++++++十++++++HLook through lens towards light·Read scale.fiber6)To clean the lens and charging contactuse only water on a damp cloth or swabDistilled water is preferable.Do not use any chemical substancesuch as;alcohol,glass cleaner,etc..Charging contactSpecificationsExposure Range:Operational Characteristics:PEN2000 to 200mR(gamma and x-rays).1.A maximum change in sensitivity of +10%may occur underPEN5000 to 500mR(gamma and x-rays)any probable combination of the following:A)TemperaturePEN20 to 2R(gamma and x-rays).range of-20 C to +50C,B)Greater than 50,000 foot alti-PEN50 to 5R(gamma and x-rays).tude for one month,C)95%Relative humidity.2.HighlyPEN200 to 20R(gamma and x-rays).resistant to shock and vibration.PEN2mSv0 to 2mSv(gamma and x-rays).Weight:PEN5mSv0 to 5mSv(gamma and x-rays).Approx.19 grams (0.7 oz.)Accuracy:Size:+10%of true dose for Cs-137 or Co-60 gamma.PEN-200,500,Length;11 cm (4.48 inches)Energy Dependence:2mSv,5mSvDiameter:1.5 cm(0.6 inches)+10%maximum change in sensitivity for x and gamma rayenergies from 20 keV to 2 MeV.PEN-5,2,20Length;11.5 cm(4.52 inches)Rate Response:Diameter:1.5 cm (0.6 inches)Dosimeters are dose rate independent.Material:Electrical Leakage:Barrel-carbon fiber-filled high strength electrically conductingIn the absence of radiation,the dosimeters leakage or self dis-plastic with metal clipcharge is less than 0.5%of full scale in 24 hours at 50C.AtWarranty:20C dosimeters will read background radiation.After gross2 year limited warrantyover exposure totaling up to 2000 R the leakage is less thanMade in U.S.A.Specifications subject to change5%of full scale in 48 hours at 20C.Thereafter,the leakagewill decrease to original values.S.E.INTERNATIONAL,INCCharging Voltage:P.O.Box 39Dosimeters are capable of being charged to "zero"with 140 toSummertown.TN 38483-0039 USA195 volts.Te:931-964-3561FaX:931-964-3564www.seintl.com radiationinfo@seintl.com
