Environmental Gamma Radiation Monitoring to the Nan-Ping Tantalum Niobium Mine

南平钽铌矿环境γ辐射监测

Tantalum niobium mineral exploitation is a kind of mineral resource exploitation and utilization project with radioactivity , radiocontamination prevention and cure is the point of environmental protection to tantalum niobium mineral exploitation .

钽铌矿开发是伴生放射性矿资源开发利用项目，放射性污染防治是钽铌矿开发的环境保护重点。

Monitoring to the first stage of the Nan-Ping Tantalum Niobium Mine shows that after exploitation , most radioactivity concentrated onto refined tantalum niobium ore , and the environmental gamma radiation level around the ore district show no remarkable difference with the level before exploitation .

对南平钽铌矿采选一期工程（600t/d）监测表明，钽铌矿的开发后放射性主要集中在钽铌精矿中，而矿区周围环境γ辐射水平与开发前比较无明显变化。
