Are used to measure the radioactivity in the environmental samples . preliminary gamma spectrometry analysis results will be available within 15 - minutes upon delivery of the samples ，量度环境样本中的辐射水平。初步的伽马谱法分析结果可在样本送抵后的十五分钟内完成。
During the ceremony , the governor of gaza province , djalma louren ? o , called for increased portuguese investment , not only in tourism but in all areas of the mozambique economy 会议期间，加扎省省长德伽马?洛伦索要求葡萄牙不仅在旅游业，而且在莫经济领域的各个行业增加投资。
As it is necessary to obtain timely information , early phase monitoring focuses on the measurement of ambient gamma dose rates , concentrations of gamma - emitting radionuclides and gross alpha beta levels 因为需要及时提供有关辐射水平的资料，早期辐射监测会集中量度环境伽马剂量率伽马放射性核素活度浓度及总阿尔法及贝他活度浓度。
Even then the european expeditions would seem paltry by comparison : all the ships of columbus and da gama combined could have been stored on a single deck of a single vessel in the fleet that set sail under zheng he 且这些欧洲船队与他相较仍是小巫见大巫：光是郑和旗下其中一艘船的一面甲板，就容纳得下哥伦布与达.伽马所有的船只。

Under the programme , air , water , foodstuff , soil and other samples are collected and analyzed regularly for their radioactivity content . ambient gamma radiation levels are also measured at a number of places over the territory 在计划内，天文台定期收集及分析空气水食物土壤和其他环境样本，以测定其所含放射性物质的水平，并且在多个地点测量环境伽马辐射水平。
The data of natural gamma ray spectrum logging are of well conformity with the contents of thorium , uranium and potassium obtained by surface gamma ray survey , laboratory analysis and aerial gamma ray spectrum survey 对自然伽马能谱测井仪、地面伽马能谱、室内分析、航空伽马能谱测量的同一地点钍、铀、钾元素含量进行对比分析得知，各种方法所得结果具有较好的一致性。
