- Property that burned had regulatory troubles and lax oversight since the 1970s
- Investigators taking closer look at federal and local records
The operator of a closed radioactive waste dump that caught fire in southern Nevada last weekend was troubled over the years by leaky shipments and oversight so lax that employees took contaminated tools and building materials home, according to state and federal records.
A soundless 40-second video turned over by the firm, US Ecology, to state officials showed bursts of white smoke and dirt flying from several explosions on 18 October from the dump in the brown desert, about 110 miles north-west of Las Vegas.
