Hole In Arctic Ozone Larger Than Ever Before

The ozone layer over the Northern Hemisphere is offering less protection than ever before, the journal Nature reports in the issue published on 2 October.  Researchers discovered that the hole that developed over the Arctic this year was about two million square kilometers in size, similar to the hole that appears each spring over the Antarctic. The ozone layer was discovered in 1913.  It is located in the stratosphere, between 10 to 20 miles above the Earth’s surface, where it absorbs most of the sun’s high frequency ultraviolet light.  Holes in the ozone layer are thought to expose people below to greater levels of cancer and cataract-causing UV radiation.  Nature’s study shows that people in Norway, Greenland, and areas of northern Russia were most at risk. Most holes in the ozone layer … Read entire article »

Fukushima Nuclear Power Plant Update

At the Fukushima Daiichi Nuclear Power Plant in Fukushima prefecture, preparations are being made to open the door to reactor number 2, which will result in radiation being leaked. However, Tokyo Electric Power Co, TEPCO, said on Saturday that radioactive water from the number 2 reactor was leaking into the sea from a cracked pit there. Once the door is opened, workers should be able to install a cooling system, and other equipment so that an explosion can be prevented, or at least the risk of an explosion be reduced. In the meantime, a massive clean-up continues, and the race is on to remove some 110,000 tonnes of highly radioactive water from the site before it can overflow. On Saturday the process had to be stopped after just 5 hours, when the … Read entire article »

Cellphone Use May Cause Cancer, New Study Reports

The controversy into the use of cellphones and its link to cancer and brain tumors continues with the latest announcement on Tuesday from the International Agency for Research on Cancer, IARC, that cellphones are possibly carcinogenic to humans. This comes after a week of meetings in Lyon, France where experts reviewed the possible links between the electromagnetic radiation which is found in cellphones, microwaves and radar, and cancer. The assessment was reached by 31 scientists from 14 different countries using dozens of published studies, and now proceeds to WHO the World Health Organization, of which the agency conducting the review is a branch. Cellphones were classified in category 2B by researchers, along with other items such as DDT which is a pesticide, and gasoline exhaust fumes, and this category is put … Read entire article »

CT Scans Exposing Children to Too Much Radiation?

In an online study released this week in the Radiology journal, researchers reported that during emergency room visits in 2008 children underwent five times more CT scans, X-ray computed tomography scans, than they did some thirteen years before. Also 90 per cent of the examinations were performed in hospitals that do not specialize in pediatrics. On top of this, the number of abdominal scans grew at a faster rate than head scans, and this is of great concern, since abdominal scans expose the child to seven times more radiation than when scanning the head. Now this report comes at a time when radiation scares persist throughout the world. Radiation is escaping from the Fukushima Nuclear Power Plant as a result of the earthquake and then the tsunami damage in north eastern … Read entire article »

West Coast of Canada – Fears Of RadioActive Contamination

There is a growing concern amongst Canadians on the West Coast, and indeed US residents living in Washington State and on the west coast of the US, that radioactive contamination from Japan’s nuclear reactors may cause problems in these countries, never mind in Japan. However, although officials in Japan have evacuated more than 170,000 people from around the Fukushima Daini Nuclear Plant, and the risk of exposure there is high, the West Coast of North America should not be too concerned as things stand at present. On Saturday, the Washington State Board of Health in Olympia commented that there is currently no human risk in Washington State, although officials are conducting monitoring as a precaution. It is believed that even if there were radiation leaks blown this way, the risk of … Read entire article »
