Australia's New EMF Exposure Standard: Five Conceits

At a time when there are calls for tightening EMF power-frequency exposure standards to address cancer risks, Australia is moving in the opposite direction. In mid-May, a committee working under ARPANSA, the national radiation protection agency, distributed a draft proposal that would triple the permissible exposure levels for the general public. If these rules are adopted, children could be exposed to up 3 Gauss (3,000mG), 24/7 –that's one thousand times higher than the 3mG threshold for childhood leukemia indicated by epidemiological studies.

How did this come about? We think it's all about conceit. Conceit about what we know and what we don't know; conceit about conflicts of interest and industry-inspired notions of precautionary policies.

Energy saving products at Expo awaken eco-awareness
2009-05-26 16:18 BJT
During the weekend starting May 22, the 12th China Beijing International High-Tech Expo received a large number of visitors. Besides displaying fantastic high technologies, the latest-model products for energy saving were also exhibited in the energy saving and emissions reduction hall, raising the eco-awareness of many people.

Most people usually do not pull the plug out of their household appliances after they have turned them off; however, this little "lazy habit" costs every family in China 60 yuan per year in standby power consumption. A series of energy saving electrical sockets named "little housekeeper" was exhibited at the expo, which can solve the problem of standby power consumption. Reporters learned that this series of wall sockets can reduce the standby power consumption to zero, with a power-saving rate of 10 to 40 percent. Not only can these sockets save electricity when appliances are in standby, but with its intelligent chip, they can save electricity while appliances are in use. These sockets can also eliminate electro-magnetic radiation.

Setback aims to keep noise at 'library' levels Increasing the distance between turbines, homes to 550 metres may harm projects, developers say

Setback aims to keep noise at 'library' levels

New rules proposed by the Ontario government would forbid the placement of large wind turbines closer than 550 metres to a residence, a distance that could affect the economic viability of many wind projects across the province.

The province-wide regulation would create for the first time a minimum setback distance for wind turbines from dwellings, roads, railway lines, wetlands and other environmentally sensitive lands or airspace.

Wind turbines emit noise and some rural residents have complained the massive machines are disrupting sleep and making people sick. The proposed setback aims to keep noise levels below 40 decibels, which, according to the government, is a level "experienced in a quiet office or library."

Sean Whittaker, policy director at the Canadian Wind Energy Association, said the 550-metre setback is not a surprise. He said Energy and Infrastructure Minister George Smitherman had already publicly stated that 500 metres would likely be a starting point.

"Our members right now are going through the guidelines and determining what impact they'll have on their projects," Whittaker said. "We will be providing feedback to the government through the normal review process."

The ministries of environment and natural resources will hold information meetings at six locations across Ontario this month, where the public will get a chance to voice their support or concerns.

Wind Concerns Ontario, a coalition of citizens who oppose industrial wind development, called the proposal a "promising move in the right direction" but urged the government to go further. In recent months, members of the group have called for mandatory setbacks of 1,500 metres or more.

Coalition spokesperson Beth Harrington said the setback should be measured from property lines, not from the actual place of dwelling. She added that the proposed regulation does not adequately address low-frequency noise or deal with individuals affected by existing wind-turbine developments.

The required setback for new projects could run as high as 1,500 metres if a cluster of 16 or more turbines emit a combined manufacturer's decibel rating of 106 or more, but experts called that an unlikely scenario that is already a possibility under existing regulation.

David Timm, vice-president of strategic affairs at Toronto-based wind developer AIM PowerGen, said a developer could reduce the setback distance down to the 550-metre minimum by proving through a noise study that actual sound is below 40 decibels.

Timm said those noise studies and the 40-decibel target are common in the industry. What developers must now come to grips with is a province-wide minimum setback of 550 metres even if noise levels are proven to fall below 40 decibels.

"Noise issues are very site specific," he said, adding that minimum setbacks were generally between 300 and 450 metres when municipalities controlled the process.

Whittaker said that adding another 50 or 100 metres to setbacks might not seem like much, but it can ruin the business case of a wind project when combined with other planning constraints.
