\rFD-3022-I <\/span>便攜式地面多道伽瑪能譜儀采用大體積的<\/span>BGO<\/span>晶體探測器和多道分析器，一體化防水設計，重量輕，靈敏度高，無源自動穩譜，可巡測及快速測量，數據自動存儲于內存中，也可以將數據導入個人電腦對數據進行回放。<\/span><\/span> \r<\/p>\r

\r本產品主要用于測量地面、巖石中的天然鈾、釷、鉀的含量及分布數據資料，以便指導地質勘察工作。適用于現場測量天然放射性核素，可通過現場同時測量巖石中鈾、釷、鉀含量來勘查礦產和解決地質問題。作為一種現場快速分析儀器，測量時間短，分析成本低，因而廣泛應用于鈾礦勘查及環境輻射監測。<\/span><\/span> \r<\/p>\r
