Indian Nuclear Scientists death mystery: Around 680 employee deaths during the last 15 years.

Hundreds of deaths of scientists involved in the Indian nuclear program remain 'unexplained' and later they declared as suicide, unnatural deaths and some cases are not resolved at or closed.

Nuclear scientists are the world’s most coveted assets during and after World War II.
heir targeting may even have begun with the “father of India’s nuclear program,” Dr Homi Jehangir Bhabha in Air India Flight 101, which crashed into Mont Blanc on January 24, 1966, killing 117 passengers and crew members. In a 1965 interview to All India Radio, Bhabha had said if he had the green signal, India could make a nuclear bomb in 18 months. The fateful plane crash took place three months later.

From there to know total death count is around 700(the BARC has reported no fewer than 680 employee deaths during the last 15 years.)

In those cases, some will blow your mind,
1. In 2013, two chief engineers assigned to India’s first nuclear-powered submarine INS Arihant, KK Josh and Abhish Shivam, were found lying on railway tracks by workers. It was suggested that they might have been killed elsewhere, perhaps poisoned, before being put on the tracks to make their deaths appear accidental or as the result of suicides.
2. In April of 2011, a 63-year-old former scientist and former head of the Indian Women Scientists’ Association, Dr Uma Rao, was found dead.
3. M Iyer, a BARC engineer who was found dead at his residence in South Mumbai. He was found to have internal haemorrhaging to his skull.
4. 24-year-old scientist Mohammad Mustafa was found dead with slit wrists at the Center for Atomic Research Kalpakkam.
5. Two other young researchers, Umang Singh and Partha Pratim Bag were burned to death in a BARC lab that reportedly contained no flammable materials.
6.47-year-old senior scientific officer L Mahalingam was working at the Kaiga Atomic Power Station.

and also within a 15-year period, the Indian Space Research Organization also lost 684 personnel or 45 deaths per year.
the death ratios are
The Baroda Heavy Water Plant reported 26 deaths, and plants at Kota and Tuticorin reported 30 and 27 deaths respectively in the same period. During this period 92 persons employed with the Indira Gandhi Center for Atomic Research Kalapakkam have died, and an RTI query by the petitioner found 16 of those deaths to have been suicides. 

what made them to death?
Conspiracy theorists point to everyone from the CIA to Pakistan’s ISI (Inter-Services Intelligence) as behind the mysterious death.
Doing so would not only keep India from consolidating its status as a regional superpower but also keep it dependent upon the US for its nuclear needs.

We can say that the other nation don't want India to be a superpower nation from the beginning as baba says.
