The test succeeded in liberating large quantities of natural gas ; however the resulting radioactivity left Causation the gas contaminated and unsuitable for applications such as cooking and heating homes .

although projected public radiation exposures from commercial use of stimulated gas had been reduced Cause_change_of_position_on_a_scale to less than 1 % of background , it became Becoming clear in the early 1970s that public acceptance within the u.s. of any product containing Cause_to_be_included radioactivity , no matter how minimal , was difficult if not impossible .

A January 2005 report by the DOE stated Statement that radioactivity levels were normal at the surface and in groundwater , though a later report due in 2007 was expected to more fully explore if there was subsurface contamination and whether or not radioactivity was still spreading Dispersal outward from the blast site itself .

In both cases the gas radioactivity was still seen Perception_active as too high and in the last case the triple-blast rubble chimney structures disappointed the design engineers .
