Radiation in Sunanda Pushkar’s viscera samples was within permissible levels and did not cause her death, the FBI has said in a report submitted to authorities .

Sources who have seen the report also said it identified the poison that killed her, but refused to name it at this stage.
The report was delivered in a sealed envelope nine months after the samples were sent to the American investigation agency’s “well-trusted lab” in Washington. It virtually rules out death by polonium poisoning — one of the many theories surrounding the mysterious death of the wife of former Union minister Shashi Tharoor in a Delhi hotel two years ago.
The report also names the radioactive isotopes that were detected in Pushkar’s body during the post-mortem examination but could not be identified in Indian labs, the sources said.
The isotopes may have been generated from a drug that was taken either orally or injected, sources quoted the report as saying.
