A person affiliated to Tamil
Nadu’s Marumalarchi Dravida
Munnetra Kazhagam(MDMK), who had immolated himself on Saturday while
protesting against the upcoming India-based Neutrino Observatory (INO) project
in Theni district, succumbed to burn injuries on Monday. His death is yet
another twist in India’s quest to set up one of its most ambitious scientific
research facilities. Initially planned
to become operational in 2020, the INO, designed to detect and study the
properties of neutrino, has been delayed by several years, due to a variety
of reasons, including protests by locals,
and the last year’s decision of the
National Green Tribunal to suspend the environmental clearance pending a
wildlife approval for the site which is barely five kilometres from a national
park.
The environmental clearance was
reinstated a couple of weeks ago by the Ministry of Environment and Forests,
but that triggered a fresh round of protests from people who believe the project poses health risks to the local
population. Similar opposition had compelled the project to be relocated once, from a site near Mudumalai National Park, north of Ooty,
to its current location in Bodi West
Hill area, Theni district.
In a statement, the INO said that
the protests, and death of the political worker, were a result of
“misunderstanding of the facts”, and promised to continue its effort to make
people aware about the project. “We are deeply pained by the self-immolation
attempt by Shri Ravi. No protest should warrant placing one’s own life in grave
danger. We believe that this traumatic turn of events was triggered by a
misunderstanding of the facts about INO. We will do our utmost to educate our
brothers and sisters, and fellow citizens in the area, so that such an incident
never happens again. INO project is meant to add to the knowledge base of
science and not to imperil the lives and livelihoods of people,” the statement
said.
The Project
The INO project involves the construction of an underground neutrino
detector, to be placed about 1.5 km below the earth’s surface. Neutrinos — not to be confused with
neutrons that, along with protons, are found inside the nucleus of an atom —
happen to be the second most abundant
particle in the universe, after photons, or light particles. Yet, they are
one of the most difficult to detect
because of their extreme inertness.
They have an extremely low tendency to interact with other objects, and simply
pass seamlessly through any object that comes in their way, including human
beings and machines that are placed to detect them. Going underground, however, slightly increases their chances of being
“seen” because of the absence of noise and other kinds of disturbances.
A large number of neutrinos
present in the universe are believed to have been produced at the time of the Big Bang, making them good candidates to extract more information
about the origins of the universe. Neutrino research is one of the most
exciting areas in physics as of now, and yielded Nobel Prizes in 2002 and 2015.
Several research groups in other countries are dedicated to the study of
neutrinos, which scientists believe, may be holding important clues to some of the basic questions about
the universe.
The INO project is being executed by a research group based at the
Tata Institute of Fundamental Research in Mumbai, in collaboration with 25
other scientific institutions.
The Hurdles
The project has been mired in one
problem or the other for about a decade. The laboratory was initially planned
to be set up in Singara (near Ooty), in
the Nilgiris. This site was suggested by the Geological Survey of India
based on the requirement of a large underground facility. Two hydel power
stations — one functional, the other abandoned — in the vicinity had ensured
that some infrastructure, including a series of tunnels, were already present.
But the nearby Mudumalai National Park
was declared a tiger reserve during the same time, and environmental
clearance to the project was denied for this reason.
The project has also faced stiff
opposition for a variety of reasons. While some people argued that the project was actually a decoy for storing nuclear
waste, others raised concerns about the possibility of nuclear or
radioactive emissions. None of it is true, and a substantial part of INO’s
current activity involves mass awareness exercises.
The current round of protests is
about something different. MDMK chief Vaiko was quoted by local newspapers as
saying that the construction of tunnels at the site would affect the stability
of the Idukki dam, some 40 km away. There are also complaints that the project
would contaminate the groundwater at the location. “None of this is correct again.
We have been making sustained efforts to inform the people about the project,
and how things that they are being told are not correct. We will have to
continue these efforts,” project director of the INO Vivek Datar told The
Indian Express.
The Fate
Complying with the directives of
the NGT, the INO applied for a wildlife clearance in January this year. The
clearance is yet to come. A couple of more clearances from the Tamil Nadu state
government are also awaited. Work can begin only after all the clearances are
received. Meanwhile, the project completion date has now been pushed back, at
least to 2023. Datar said it would take
about five years to build the first stage of the detector after construction
works start, and another two years for the second and final stage. “We will
try to expedite construction work as much as we can. But that can happen only
after we get the final approvals from everywhere,” he said.
