Workers at a West Texas nuclear waste disposal site are closely monitoring containers being stored there temporarily, a day after New Mexico officials said containers packed with organic kitty litter may pose a potentially "substantial" threat to public health.
One container with the litter is believed to have caused a radiation leak at the federal government's troubled nuclear waste dump near Carlsbad, New Mexico.
Waste Control Specialists spokesman Chuck McDonald says the containers from Los Alamos National Lab are being monitored by video camera. He did not know how many containers were at the Andrews County site in West Texas.
The containers came to WCS after a leak elsewhere contaminated 22 workers with low levels of radiation in February.
The kitty litter soaks up any liquid before drums of waste are sealed.
