NEW DELHI — A man hospitalized for radiation exposure died Monday night from multiple organ failure, the first fatality stemming from a major case of radiation exposure earlier this month that forced authorities to temporarily cordon off an industrial area near the heart of the national capital.

The man, who used only a single name, Rajender, died in the intensive care unit of the All India Institute of Medical Sciences after blood transfusions and other treatments failed to reverse his deteriorating condition. A hospital supervisor said the patient suffered from pneumonia, liver and kidney failure and other related problems.

Rajender, 35, was one of seven people hospitalized after being exposed to radioactive materials at scrap metal shops in an industrial area known as Mayapuri, located barely 10 miles from India’s Parliament.

Indian officials believe the source of the radiation was a piece or pieces of outdated medical equipment hidden in a shipment of scrap metal imported from overseas.
