The home radon testing season is drawing to a close

house Radon is an invisible, odourless, naturally occurring radioactive gas. It can enter homes, schools and other buildings through foundation cracks and long-term exposure may lead to lung cancer.

If you order a test kit today, the majority of the long-term test period would fall outside of the heating season. It is strongly recommended that you wait until the fall to test your home for radon.

Buy Lunesta No Prescription

Buy Lunesta No Prescription, There has been a lot of news in recent days about the new security measures in airports following the incident onboard Northwest Airlines flight 253 on Christmas Day last year. Where can i order Lunesta without prescription, As a result, some airports have started using new full body scanner technologies, purchase Lunesta online no prescription, Buy Lunesta from mexico, such as backscatter x-ray scanners and millimeter wave scanners. This has led to concerns in the public about potential health effects, where can i buy cheapest Lunesta online, Buy cheap Lunesta no rx, but is there any reason to be concerned about radiation exposure.

The first thing you need to know about these scanners is that the two technologies are very different, order Lunesta. Where can i buy Lunesta online, Whereas backscatter x-ray scanners use x-rays to image, and being exposed to high levels of x-rays can lead to adverse health effects, buy Lunesta online no prescription, Lunesta over the counter, millimeter wave scanners use waves of much, much lower energy, australia, uk, us, usa, canada, mexico, india, craiglist, ebay, paypal, Buy Lunesta in canada, and will not lead to adverse health effects. Learn more about the differences between the technologies and how to recognize them here (coming soon), Buy Lunesta No Prescription.

We will focus here on backscatter x-ray machines, Lunesta from canadian pharmacy. Order Lunesta online c.o.d, To understand the potential risks, it is important to know what backscatter x-ray scanners actually are and what they do, order Lunesta no prescription. Order Lunesta from mexican pharmacy, These machines use x-rays to give security personnel an image of the exterior of a passenger's entire body. The idea is to reveal anything someone is carrying under their clothes, online buying Lunesta, Lunesta samples, particularly liquid explosives, weapons, where can i find Lunesta online, Buy no prescription Lunesta online, and drugs. Buy Lunesta No Prescription, These scanners are similar to medical x-ray machines only they operate at a much lower energy. This means that the radiation dose a person would receive from a backscatter x-ray scan would be much lower than the dose received from a medical x-ray, buy Lunesta no prescription. Buy generic Lunesta, Another difference is that in medicine, the radiation that passes through your body is used to create the picture, Lunesta pharmacy. Buy Lunesta without a prescription, Backscatter technology uses the x-rays that scatter (or "bounce") off the surface of your body, as well as any objects next to it, rx free Lunesta, Online buy Lunesta without a prescription, to create the image. There is more detailed information about this technology on the website of American Science and Engineering (AS&E), purchase Lunesta online, Buy Lunesta online cod, the manufacturer of these scanners.

The health risks for air travellers from this technology is negligible, Buy Lunesta No Prescription. Whenever radiation is concerned, Lunesta for sale, Lunesta price, people are most often concerned about increasing the risk of developing cancer. AS&E states that the dose delivered to a passenger is less than 0.1 micro sievert (µSv) per scan, buy cheapest Lunesta. A µSv is a unit used for measuring radiation dose. A typical dental x-ray can deliver a dose of 0.01 milli sievert (mSv) to a patient. Buy Lunesta No Prescription, That's 10 µSv. In other words, it would take 100 backscatter x-ray scans to deliver the same radiation dose as a dental x-ray. In fact, the National Council on Radiation Protection and Measurements (NCRP) of the United States says that 0.01 mSv of radiation dose per year is a negligible dose to an individual.

The sun and radioactive materials naturally occurring in the Earth as well as in the air all contribute to our overall radiation dose. In fact, each of us receives about 3 mSv per year from natural "background" sources of radiation like the sun. Indeed, when flying on an airplane, the average passenger receives a higher radiation dose than those travelling by ground, Buy Lunesta No Prescription. How much more. There are many factors that affect the dose, but a low estimate is that for every hour flown in a commercial airliner, passengers receive a dose of 3 µSv per hour. So, one hour of flight is roughly equivalent to 30 backscatter x-ray scans.

Protecting your family from radon gas

As Canadians, we all want the cleanest, safest, most secure home environment to live in and raise our families. One way to do this is to monitor our homes for the quality of the air we breathe. Radon gas is not something we hear about every day in Canada however, radon exposure is a leading cause of lung cancer – second only to smoking.

Ontario Lung Association warns of radon risks

As winter weather approaches and we move activities indoors, it’s a good time to think about the quality of the air in our homes. Radon is a colourless, odourless gas that is produced from the natural breakdown of uranium in rocks and soil.

Radiation Safety Institute Promotes Radon Awareness at Fall Home Show

For most of the homeowners and would-be do-it-yourself-ers attending the 2009 Fall Home Show in Toronto, the issue of radon in the home came as something of a revelation.

WHO slashes radon limit in homes, cites lung cancer risks

The World Health Organization (WHO) has drastically cut the maximum amount of radon, a naturally occurring gas, that should be permitted in homes because of strong evidence it causes lung cancer.
