Mobile Phones (Health Effects)

Debate between Lord Watson of Wyre Forest and Anne Milton

Monday 20th December 2010 Commons Chamber

[Anne Milton]

I thank the hon. Gentleman for his intervention, but may I suggest that he may be jumping the gun a little? I have been speaking for only about two minutes, and I will come to all those issues if he gives me a bit more time.

The independent expert group on mobile phones and health was set up in 1999, partly as a response to public concern. It was tasked with reviewing the health effects of mobile phone technology. As a newly elected councillor, I was acutely aware of the considerable concerns among people in my ward at that time. As has been mentioned, the group was chaired by Sir William Stewart, the former chief scientific adviser to the Government. Its report was published in May 2000.

The report was based on a thorough review of scientific evidence on the health effects of mobile telephones and it took account of work in progress, alternative views on the science and public opinion, which at that time was considerably concerned about those effects. In 2004, the then National Radiological Protection Board reviewed the evidence again—the hon. Member for West Bromwich East mentioned this—and reiterated Stewart’s recommendations, in particular the recommendation that a precautionary approach should be adopted. Current Government policy on mobile phones is based on the Stewart report and its recommendations. The headline conclusion in the Stewart report was that

“the balance of evidence to date suggests that exposures to”

mobile phone “radiation below” national

“guidelines do not cause adverse health effects.”

The report was referring to the National Radiological Protection Board national guidelines, which were in place at the time. It is none the less important to note that Stewart recommended that as a precautionary measure the guidelines should be replaced by more restrictive international guidelines.

In recognition of the incomplete scientific knowledge and significant public concern, Stewart made other precautionary recommendations. For example, he recommended that the widespread use of mobile phones by children for non-essential calls should be discouraged. As the hon. Gentleman said, however, warnings are difficult to find, and the small print is very small. I suspect that many people these days are unaware of that guidance. I shall return to the question of scientific evidence in a minute.

The Government accepted the advice of the Stewart report and followed a precautionary approach, and most of the recommendations were implemented in full. On Stewart’s recommendation, we moved to stricter international guidelines for exposure. Along with other member states, the UK supports the European Council recommendation to limit exposures to electromagnetic fields, which incorporates international guidelines. By 2001, industry, Government Departments and their advisers were working to the new exposure guidelines for mobile phone technology, so now all mobile phones and base stations comply with the guidelines.

An important development following the Stewart report was the setting up of a new research programme in this country—the mobile telecommunications and health research programme, or MTHR. Research has been carried out at centres throughout the country under the management of an independent programme management committee. It is important to mention that it is independent. In 2007 MTHR published a report from 23 completed projects. Since then, further work has been published from the programme.

MTHR is a very high-quality research programme and none of the research so far has shown that radio frequency emissions from mobile phones affected people’s health—at least in the short term, although that is obviously not the end of the story. The lack of long-term data, however, has been noticed by MTHR, the World Health Organisation and other regional and international advisory committees. It is also being addressed by an international cohort study on mobile phone use and health known as COSMOS, to which the hon. Member for West Bromwich East referred.

The UK forms a key part of the study, and our participation is funded under the MTHR programme. I understand that the COSMOS study aims to follow the health of approximately 250,000 European mobile phone users for up to 30 years. It is a very thorough process. COSMOS will consider any changes in the frequency of specific symptoms, such as headaches and sleep disorders, over time as well as the important risks of cancers, benign tumours and neurological and cerebrovascular diseases.

The Department also supports the World Health Organisation’s international electromagnetic fields project, which encourages research focused on specific gaps in our knowledge. There is no doubt that there are considerable gaps in our knowledge at this stage. Apart from the accident risk from using mobile phones when driving, present knowledge indicates no proven risk to health from mobiles, except of course in the easy access that one has to home delivery pizzas and the possible impact on our daily calorific intake, which cannot be ignored.

Let me address for a moment mobile phone base stations, which are often called masts. When I first entered politics as a local councillor, that was one of the subjects that caused most concern. Masts provide the communication links by radio waves to handsets, allowing connection to the rest of the telephone system and the wider world. Mobile phones need this infrastructure to function, and it is this infrastructure that has caused so much concern in the past. On masts in particular, Stewart concluded that on the balance of evidence there is no general risk to the health of people living nearby, on the basis that exposures are expected to be very small. However, it is of note that in that connection, too, he recommended a precautionary approach. It was interesting to learn from the Stewart report that the levels of radio frequency exposure from masts, which people thought were likely to be high, were much lower than those from mobile phone handsets held near the head. Indeed, yearly independent audits have shown that mast exposures are well below the international guidelines—in many cases tens of thousands or more times below.

The MTHR also reaffirmed that exposures from base stations were very much lower than international guidelines. An MTHR study specifically looked to see whether short-term exposure to radio frequencies from masts could affect people’s health. Although some people attribute their ill-health symptoms to mobile phone base stations—the hon. Gentleman raised this issue—the MTHR peer-reviewed study found no convincing evidence so far that their symptoms were caused by exposure to signals from mobile phones or masts. But, of course, we should not and shall not be complacent: we must continue to keep the science under review. The Health Protection Agency keeps us informed of the science in this area, and its independent advisory group on non-ionising radiation is currently reviewing worldwide scientific studies on radio frequency emissions as part of its regular review cycle, and will report in one to two years’ time.

[Mr Watson]

I am grateful to the Minister for her very gracious answer to my rather long presentation. Does she think there are merits in opening up discussion with the industry on how they can improve their packaging advice and how we can improve public education, particularly for young mobile phone users?

[Anne Milton]

Yes, the hon. Gentleman’s point is well made. As I have said, most people are unaware of the guidance available, and the small print is often extremely small.

I am aware of the ability of large and powerful vested interests to lobby, often very successfully. There are, without doubt, eye-wateringly large amounts of money at stake in the mobile communications industry. I assure the hon. Gentleman that I am old enough and cynical enough to apply at all times an appropriate level of scrutiny and cynicism to all information that comes my way—always seeking to find out whence it came and who paid for it. He is right to say that no stone must be left unturned, but the problem is to establish causality. That is why, with ongoing and international studies, following a cohort is essential. We must base any Government action on robust scientific evidence. He is also right to say that it matters who funds research, and I assure him that I will not be pushed around, and I will keep my level of cynicism. However, I cannot comment on phone hacking; he must address those comments to another Minister on another occasion. Within my own portfolio, I will keep my eye on what is going on. As I say, I look forward to the report of the HPA’s independent advisory committee in one or two years’ time.

Let me conclude by saying that the Government take extremely seriously public concern over possible health risks from mobile phone technology, as they do all threats. There is a particular issue in that we are aware that health effects might not become apparent for 10, 20 or even 30 years. It is important to remain vigilant and to keep this matter at the top of our list of priorities. We will continue to respond to people’s concerns and to support those high-quality scientific studies, both nationally and internationally, in an honest, open and transparent way, being clear at all times where the vested interests lie. I thank the hon. Gentleman for raising this issue, which is of concern to so many people.

Question put and agreed to.
