摘要
人工放射源在石油勘探、开采等方面得到广泛应用，放射性核素可通过多种途径污染土壤环境。大庆油田有13个单位应用放射性物质（非密封源或密封源）。为了对大庆油田地区的土壤放射性状况进行较全面的调查，因此对土壤放射性本底、现状水平及放射源周围土壤放射性强度进行了监测，采集样品200多个，总α的测定采用饱和厚度法，总β的测定采用有效厚度法，监测结果说明原油开采应用放射性物质对土壤环境未造成不良影响。
Artificial radioactivity sources are widely applied to petroleum exploration and development and probably in ways of preventing pollution in soil environment. Thirteen sub-units of Daqing Petroleum Administration are the users of non-sealing or sealing radioactive material. Authors monitored the radioactivity background,status and radio intensity of the soil around the source,and collected samples of more than200. The saturated method is for total α measurement,while the thickness method is fortotal β measurement. The monitoring results indicate that the application of radioelements does not pollute the soil environment obviously.
