Nuclear experts have scanned hundreds of shops in Mayapuri, a west Delhi scrap market, but have not found any new radioactive source, the Atomic Energy Regulatory Board (AERB) said on Saturday.
Eleven sources of radiation were detected in the Mayapuri scrap market recently when Cobalt-60 was recovered, injuring 11 persons including three scrap dealers.
Scientists are yet to pinpoint whether the origin of Cobalt-60 was from domestic or imported scrap.
Cobalt-60 pins, recovered from the market, are not produced domestically, experts say.
A senior AERB official said that the radioactive material recovered from Mayapuri is being examined in a "remotely handled facility" at the Narora Atomic Power Station in Bulandshahr in western Uttar Pradesh.
The official said AERB is planning to thoroughly scan the market before declaring it a safe zone.
"We have already scanned all the shops in the market. It is somewhere between 600 and 800," another official said.
Cobalt-60 is a radioactive isotope of cobalt, which is a hard, lustrous, grey metal. It is used in cancer therapy machines and other medical equipment.
Cobalt-based colours and pigments have been used since ancient times for jewellery and paints. Miners have long used the name kobold ore for some minerals.
