Radiation levels have come down in the six hotspots of west Delhi's Mayapuri area but were still not normal, environmental NGO Greenpeace said Wednesday.

A team of Greenpeace surveyed Delhi's Mayapuri scrapyard in the morning and said radiation levels were much less than last week.

"As of now radiation levels are less but not normal. Bringing them to normal background levels involves detailed handling, checks and re-checks and we need to discuss the way forward," said a Greenpeace spokesperson.
