The Investigation Of Safety Running For City Radioactivity Waste Storeroom Of Ji Lin Province

The radwaste means the radioactive source and waste that produced inthe nuclear technique application, The majority degree of ratio lives is low in3.7×10~6 Bq/Kg, the radio level according to national radioactive wasteclassification standard is low level radioactive waste .The city radioactivewaste storeroom that saves the local radio solid waste and source , is a socialpublic-spirited environmental protection establishment .The character ofradioactive waste of JiLin province is temporary storeroom, among them theshort half-life radioactive waste disintegrate to attain to release value(thedegree of radio ratio live is low in 2.0×104Bq/Kg) don't need administer byrule .The waste storeroom mainly receives the low level radio solid wastewhich comes from nuclear technique application realms, such as workagriculture,research, medical treatment and teaching etc. (called radioactivewaste as follows) with no longer used or abandon radioactive source.(calleddiscarding source as follows).Analysis the movement of safety by monitor the old and new radioactivewaste storeroom,surroundings of XiaoChaJiaGou . Monitor the object coversa γ radiation air of absorbed amount rate,soil,groundwater ,the livingcreature sample aspects.1. The running circumstance of the old storeroomThe old storeroom started to set up in 1964, it handed over from hygienesection to environmental protection section after circulated 30 years , ended in1995 .It once appeared the quantity problem in its construct process and hadbeen rectified the measure recover, through many years of running and discardto use its appeared some problem again.Through the monitor, the γ radiates air ratio release the kinetic energyrate inside the old storeroom's is higher than Jilin region land 's, The outsideextends along with the scope measures to lower gradually, affecting to theenvironment gradually small2.The running circumstance of the new storeroomThe empirical summary in working for so many yearses, the newstoreroom in my province accepts the the work to the radioactive wastealready basic maturity.From accept the and manage, collect, register, transportto the radioactive waste as to it's supervise and control, pure and dirty all strictaccording to national related standard to proceed.New each cellar of the inside of storeroom room and surroundingsesmonitors to order the land γ radiates the air ratio releases the kinetic energyrate all within the scope of Jilin region land γ radiates the air absorbs measuresrate variety, belong to the normal a bottom level.Although the of individualorders the γ radiatings air is higher than releasing kinetic energy rate to alsobelong to the normal phenomenon, may have the part the pollution in acceptprocess.3. Other district in the area of storeroom and outsides are small to checkthe safe circumstance of the house ditch resident areaStoreroom area garage, transact floor, area doorway and outsides smallcheck the γ that house ditch resident area etc. monitors point radiates the airabsorbs measures rate all within the scope of Jilin region land γ radiates airabsorb measures rate variety, belong to the normal a bottom level.4. The investigation of radio nuclear element in soilIt can be seen from analysis the soil in the radioactive waste storeroom ofJilin ,the238U,232Th,40K in the new and old storeroom's surrounding are allwithin the scope of Jilin region 's and belong to the normal bottom level. Onlythe 226Ra is higher than environment's bottom and imply the artificial elementof 90Sr and137Cs, because they have polluted the environment slightly . Thereis not artificial element of 90Sr and137Cs in the new storeroom.5. The investigation of radio nuclear element in groundwaterThe natural radio element of 238U,232Th,226Ra, 40K in the storeroom andXiaochajiagou's are all within the scope of Jilin region 's and belong to thenormal bottom level. Total α , total β and artificial element of 90Sr and137Csinside in groundwater all under the bottom scope of Jilin6. The investigation of radio level in living creature sampleCollect the living creature sample Radiates around the storeroom tosolute the environment condition of Jilin province radioactive storeroom, fromexamination, it belongs to the normal bottom level.Conclusion:1) The old radioactive waste city storeroom of Jilin provincestoreroom that have stopped using because of the building problem ,acceptance and manage etc . It has couldn't deposit the wasts, and has hadbetter tore down early. 2) The acceptance and manage in the new storeroom issafety and valid , and fit to the laws that manage the radioactive wastes in ourcountry. It can be further perfect and related measure.3) The environment ofstoreroom area surroundings and XiaoChaJiaGou fit the national normalstandard completely, the radioactive waste city storeroom of Jilin province cityradioactive waste storeroom is not lead to bad influence.
