Kudankulam: a settled issue








Kudankulam: a settled issue
Concerns of activists about the independence of the Atomic Energy Regulatory Board are misplaced

First Published: Sun, Jun 16 2013. 08 13 PM IST






Criticizing nuclear power as an inherently dangerous energy source is now a fashion in the
world.Such criticism is especially pernicious and misplaced in an energy starved country like India.
One way of holding nuclear energy as an unsafe option is to claim that nuclear regulation in India is weak and the regulatory authority, the Atomic Energy Regulatory Board (AERB), is not independent and is marred with conflicts of interest due to its organizational structure. Nothing could be further from the truth.
In a recent article (Kudankulam: the unsettled queries, Mint, 5 June), M.V. Ramana has tried to attempt to divert readers’ attention from the far-reaching, landmark judgement of the Supreme Court on setting up of the Kudankulam nuclear power plant. Based on the existing legal framework, the court decided the unsettled (or settled) queries on matters related to nuclear power in India.
It has been asserted that the apex court ventured beyond its brief and commented on areas that were outside its provenance. This is not true. The unease of Ramana and his fellow activists is understandable. The court only gave judicial sanctity to the necessity of setting up nuclear power plants in India as it is the national policy implemented by the government, which is empowered to do so by the Atomic Energy Act 1962. 
The views of anti-nuclear activists are often inconsistent. For example, Ramana does not see anything wrong in the Comptroller and Auditor General (CAG) inappropriately commenting on how AERB should be structured even when the Parliament is considering a Bill to address the issues effectively.
The fact is that AERB enjoys de facto autonomy. It has shut down operating nuclear power plants, reduced the power of some plants and stopped construction of projects on several occasions when it felt that safety was compromised. 
This writer once counted 50 such instances. For example, the Nuclear Power Corp. of India Ltd (NPCIL) was forced to comply with some of the restrictions prescribed by AERB, a step that led to the loss of millions of rupees in revenue for the former. Had AERB been a toothless body that it often is claimed to be, it could never have ensured such steps. AERB was never found wanting whenever the need arose. In the heat of activism, these inconvenient facts are often ignored.
The apex court did not find any frailty in the legal framework. The assiduously maintained perception of nuclear critics that AERB is not independent did not sway the court. The court determined that for setting up the project, the project proponent took all safety requirements on site and off site and followed the code of practices laid down by AERB, based on nationally and internationally recognized safety methods.
The court relied on the unanimous opinion of expert committees that there will not be any deleterious effects due to radiation from the operation of Kudankulam plant, and that adequate safety measures have already been taken. 
Another point of contention among anti-nuclear activists is that there is little nuclear expertise outside the department of atomic energy (DAE) to constitute an independent Nuclear Safety Regulatory Authority. This would indeed be an issue if AERB was a toothless body. But, as argued above, this is not the case. AERB has over 220 highly qualified and competently trained officers, over 50 of them with more than 15 years of experience in nuclear and radiation technology.
The court endorsed the stand of AERB and its committee that given the robust safety features of Kudankulam reactors, which belong to generation-III plus category, the recommendations of AERB expert committee are only for safety enhancement as a matter of abundant caution.
AERB has also been faulted for permitting loading of fuel even though the recommendations of its committee had not been fully implemented at Kudankulam. 
After the fire incident at the Narora nuclear power in Uttar Pradesh in March 1993, it was felt that roots of the turbine blades of the pressurized heavy water reactors must be inspected. Based on a technical review, AERB allowed Nuclear Power Corp. to shut down the reactors sequentially for inspection and not simultaneously. AERB applied its engineering judgement on the issue and that did not compromise safety in any manner. From this perspective, the happenings at Kudankulam are not unusual or even suspect.
NPCIL got a shot in its arm when the Supreme Court declared that the corporation, while setting up the power plant at Kudankulam, had satisfied environmental principles such as sustainable development, corporate social responsibility, inter- and intra-generational equity and so on to further the implementation of the policy to develop, control and use atomic energy for the welfare of citizens and for the economic growth of the country. 
This should rest the fear that establishing a nuclear power plant at Kudankulam will make inroads into the right to livelihood guaranteed under Article 21 of the Constitution. If anything, establishing such a plant will only protect the right to life under this article by achieving larger public interest. The court has said this very clearly.
The court did what was best for the country. If national policies, decided by elected representatives and executed by legally responsible agencies, are challenged on the grounds of perception by small groups, however well-intentioned they may think they are, we will not progress in any field. Ramana advises us passionately, persistently and persuasively. That is to be admired. But we need not accept his advice in national interest. For the moment, Kudankulam is a settled issue.

Cell tower radiation and cancer clusters


Cell tower radiation and cancer clusters
By Dr K S Parthasarathy
PTI Feature
PF43/2013  dated March 23, 2013
Cell tower radiation has a million times lower energy than x-rays and gamma rays which can make structural changes  in cells in the human body.
As cell towers started appearing in different parts of the country, public started  attributing  all sorts of  symptoms and diseases to them. On January 4, this year  a leading news paper  quoted the District Health and Family Welfare Officer (DHO) of Dakshina Kannada as saying that "enough number of cases of cancer and mental retardation have been found among people residing within a 500-metre radius of cell phone towers.” This observation is not scientifically supported. 

Cell tower radiation has a million times lower energy than x-rays and gamma rays which can make structural changes  in cells in the human body. Human body consists of cells; cells form tissues; several tissues join together to form organs. 

When energetic radiation such as x-rays or gamma rays interact w gamma rays, they are able to make structural changes in the cell. Large part of  radiation impinging on the body may go without any interaction. But some part of the radiation may be absorbed by the cells. It may kill a few cells. Radiation energy may partly damage them. Partly damaged cells may suffer loss of  the  precisely set, multiplication and growth control mechanisms. These cells may become anarchic with no rules at all or rules of their own! These rogue cells multiply rapidly  and proliferate uncontrollably to cause cancer. Cell tower/phone radiations  are non ionizing and  are incapable of   starting such disruptive action in the cell  because they lack energy.

Even after several decades of study, researchers could not identify any mechanism to explain how cell phone/tower radiation can cause cancer. If there is a mechanism, it will be entirely new. Cell phone technology is new. If the interaction of radiation may cause some diseases which have a  long latent period, it may take some time to manifest. This is the reason why researchers want to continue the studies for longer periods of time.

The results obtained so far are reassuring. In spite of the fact that cell phones have been used by millions of people, no notable increase in cancer or other effects have been recorded so far. 

The latest scientific review by the UK Health Protection Agency (HPA) in its report titled "Health Effects of electromagnetic radiation- RCE-20" published  in April 2012 stated thus:
"In summary, although a substantial amount of research has been conducted in this area, there is no convincing evidence that RF field exposure below guideline levels causes health effects in adults or children." The report can be accessed from the web site of the HPA.

Every physician  must read it compulsorily. Unfortunately, many physicians like lay public, get carried away by  newspaper reports and other literature. These are also freely available. A professor of electrical engineering from the Indian Institute of technology, Bombay wrote one such document titled "Report on cell tower radiation" and submitted it to the Department of Telecommunication (DOT). Apart from several unsubstantiated comments and wrong interpretation of concepts, the report contains news stories in a subsection titled "Epidemiological studies from different countries".
One story was from Australia.

 Thus:"The top floors of a Melbourne office building were closed down and 100 people were evacuated after a seventh worker in seven years was diagnosed with a brain tumour. The Australian Health Research Institute indicates that due to billions of times more in volume electromagnetic
radiation emitted by billions of mobile phones, internet, intranet and wireless communication data transmission, almost one-third of world population (about 2 billion) may suffer from Cell Phone Cancer beside other major body disorders like heart ailments, impotency, migraine,epilepsy by 2020."

I sent excerpts of the report to many specialists. "I was responsible for carrying out the EMR measurements at the building.  The final result was that the incidence of cancer in that building was the same as the general population." Mr, Chris Zombolas, the Managing Director of EMC Technologies Pty Limited, an internationally recognized company,  accredited by National Association of testing Authorities (NATA), Australia,  responded to this writer

"I believe that this is an alarmist report with many factual and technical errors.  The assertions are made without proper evidence from peer reviewed publications.", Mr Zombolas added.

"What is the reputation of the Australian Health  Research Institute?" this writer asked him.  I also asked him whether he can give  any reference or publication  conceding that the cancer incidence in the building which was evacuated  was the same as the national rate.

Mr Zombolas asserted that he has never heard  of The Australian Health Research Institute. But he sent this writer a link which claims that it is a hoax.  

Regarding the evacuated building in Melbourne, he sent the announcement from a reputable source that it was not a cancer cluster. You may access the report at:

Stories on cancer clusters and other diseases  near cell phone towers are spread by vested interests selling screens, shields etc against cell tower radiation. News papers unwittingly help them by publishing such unsubstantiated stories.

A typical example from the blog of such a company: "Do your family members feel nauseated or irritated at the simplest events? Is your child unable to concentrate on his/her studies? Is your home near a mobile phone tower? May be, it’s time to get your house inspected for radiation levels and replace your cotton curtains with options that could block radiation." 

The WHO is aware of  scary stories on increased cancer incidence near cell towers and noted thus in its Fact Sheet No 304:
“Media or anecdotal reports of cancer clusters around mobile phone base stations have heightened public concern. It should be noted that geographically, cancers are unevenly distributed among any population. Given the widespread presence of base stations in the environment, it is expected that possible cancer clusters will occur near base stations merely by chance. Moreover, the reported cancers in these clusters are often a collection of different types of cancer with no common characteristics and hence unlikely to have a common cause.”
