【摘要】 我国放射性计量与国际发展一样,最初以固体镭点源为计量标准,随后逐步建立了与测量对象近似的标准辐射场。核工业放射性勘查计量从点源发展到了实物模型标准,建立了计量标准与测量对象高度近似的γ辐射场。文章从计量标准装置和计量技术标准两方面介绍了我国放射性勘查计量的发展以及已掌握的关键计量技术,并分析了放射性勘查计量装置的现状、发展趋势。更多还原

【Abstract】 As the same with international development,radioactive standards in China have developed from the initial solid radium point source to standard radiation field which is similar to the measuring object.Radioactive prospecting metering had developed from the point source to the physical pad standards,the y radiation field of metering standard approximate that of the measuring object was established.This paper introduced the development of radioactive prospecting metering and the key metering technologies which has mastered,based on metering technological standards and metering standard device.The current situation and trend of development of radioactive prospecting metering device was analyzed.更多还原
