Samples of ore

water and soil in a copper deposit were collected. The contents of U

K

Th and other trace elements were determined by INAA

while Ra content was analysed by natural radioactivity survey. The results indicated uranium enrichment in the ores in contrast to in the soil around living area where equilibrium coefficient<1. So appropriate keeping of the copper ores was thought to be very important to protect the environment against pollution of radioactivity （uranium）. Since gold and rare-earth elements enrichment in the ores were found

a suggestion of comprehensive utilizing the copper resources was put forward.
