"A call was received from the airport around 10.45 AM regarding suspected radioactive leak from medical equipment," said Atul Garg, Chief Fire Officer.

He said the equipment has come from Air France plane and was kept at the cargo terminal.

The entire area has been cordoned off and National Disaster Management Authority (NDMA) has also been informed about the incident, Garg said.

There was no immediate response from Delhi airport authorities and Air France.  "The area is 1.5 km away from passenger area and was evacuated and cordoned off," police said.

A team from NDRF has reached the spot. A team of doctors from Medanta hospital has also been rushed to the spot.
