URANIUM MINING AND ACTIVITIES, PAST AND PRESENT Update .
Uranium Mining in Arizona – Historic Activities Navajo Nation In the 1940's and 1950's, uranium was discovered on the Navajo Reservation. Navajo men from the local community mined uranium ore for the atomic weapons program. When mining ceased in the late 1970's, operators abandoned mines without sealing tunnel openings, filling

Radiation and Mining Uranium mining releases radon from the ground into the atmosphere. Openpit and insitu mining sites have been monitored by federal agencies and found to pose a low risk to the public. However, underground mines potentially pose a higher radon risk to both the public and workers. Mines and mining waste can release radionuclides, including radon, and other pollutants to ...

· But Uranium Corporation of India Limited claims that the uranium mining and radiation are under check and haven't contributed to health hazards. Photo by Subhrajit Sen. The villagers complain that the hills surrounding Jaduguda, dug up to create 'tailing ponds,' have proven to be a severe health hazard. A tailing pond is an area where leftover material is stored after the excavated ore ...

· Results and discussion. External gamma dose rates. Even though the background gamma radiation near mining area was not very high, the stacking of massive uranium ores outside the mining pit and spilling of uranium ores from the tractortrailer transportation system, render the area susceptible to substantial high absorbed gamma dose rates. For example, the piling up of some .
Toxic Legacy of Uranium Mines on Navajo Nation Confronts ...
· Today, there are more than 520 abandoned uranium mines on Navajo Nation, and the vast majority of them have not been remediated (, cleaned up and environmentally contained). Roughly half of these mines still have gamma radiation levels more than 10 times the background level. Nearly all are loed within a mile of a natural water source ...
