Two more sources of radiation were detected in the Mayapuri scrap market in New Delhi where Cobalt-60 was recovered, taking the total sources of radioactive substance found in the industrial area to 10.
Eight sources of radioactive Cobalt-60 were detected last week while the two fresh cases of radiation were detected on Tuesday. Seven persons were injured after getting exposed to the radioactive.
Fresh radiation was detected by a team of experts from Department of Atomic Energy which was conducting follow-up checks in the market, S K Malhotra, Public Awareness Officer of DAE, told PTI on Wednesday.
"Our team from Atomic Minerals Directorate Unit was combing the area for possible radiation. We had gone there for a routine check when we detected higher than normal radiation levels in 500 metres of the shop where radiation was detected earlier," he said.
"We detected two more sources of radiation last night. However, radiation was much less in intensity this time compared to the one we detected last week," he said.
Experts were ascertaining the nature of the radioactive material.
The shopkeeper had removed some metal from scrap which is the source of fresh radiation, he said.
Soon after the radiation was detected, National Disaster Management Authority and National Disaster Response Force were alerted.
Panic was triggered in the locality last week after news of a radiation leak spread with six persons falling ill after coming in contact with a "mysterious shining object" in a scrap shop, later identified as Co-60.
A senior police official said the new source of radiation was detected "quite far off" from the earlier one which was detected on last Friday in the shop in Mayapuri owned by one Deepak Jain, who is in a serious condition in Apollo Hospital.
Asked whether it was a lapse on part of experts who conducted searches last week, he answered in the negative saying the new source of radiation was at least 500 metres from the shop where the radiation was detected earlier.
