\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(cè)器和多道分析器，一體化防水設(shè)計(jì)，重量輕，靈敏度高，無源自動(dòng)穩(wěn)譜，可巡測(cè)及快速測(cè)量，數(shù)據(jù)自動(dòng)存儲(chǔ)于內(nèi)存中，也可以將數(shù)據(jù)導(dǎo)入個(gè)人電腦對(duì)數(shù)據(jù)進(jìn)行回放。<\/span><\/span> \r<\/p>\r

\r本產(chǎn)品主要用于測(cè)量地面、巖石中的天然鈾、釷、鉀的含量及分布數(shù)據(jù)資料，以便指導(dǎo)地質(zhì)勘察工作。適用于現(xiàn)場(chǎng)測(cè)量天然放射性核素，可通過現(xiàn)場(chǎng)同時(shí)測(cè)量巖石中鈾、釷、鉀含量來勘查礦產(chǎn)和解決地質(zhì)問題。作為一種現(xiàn)場(chǎng)快速分析儀器，測(cè)量時(shí)間短，分析成本低，因而廣泛應(yīng)用于鈾礦勘查及環(huán)境輻射監(jiān)測(cè)。<\/span><\/span> \r<\/p>\r
