Radiation Protection “Chip” Introduced In India. Will You Use I
2012-01-24 10:00:00 Syenergy Environics has announced a product in the form of a Chip, which the company claims to guard oneself from electronic radiation. Christened Enviro chip, the small Printed Circuit Board (PCB) chip when affixed on a “Specific Area”, will guard the humans & sensitive electronics against radiation which is supposedly harmful & is emitted constantly while the electronic device such as mobiles, WiFi Routers etc. are in use. So, how does this Chip work? Unlike the anti-radiation stickers commonly found on mobile phones, this chip is meant to work on Active hindrance techniques. When applied to the designated area, the chip operates between 500 to 600 THz which is much higher than the radiation emitted by theelectronic devices themselves. These random generated waves are supposed to hinder the emission & the company claims that the chip protects humans by making the emissions compatible with the body’s random waveforms. How exactly it happens is not yet cl...

MRI guided radiation therapy (MRIgRT)
2009-05-24 19:29:00 At the UMC Utrecht, The Netherlands, we have constructed a prototype MRIaccelerator. The prototype is amodified 6MVElekta (Crawley, UK) acceleratornext to a modified 1.5 T Philips Achieva (Best, The Netherlands) MRI system.From the initial design onwards, modifications to both systems were aimed toyield simultaneous and unhampered operation of the MRI and the accelerator.Indeed, the simultaneous operation is shown by performing diagnostic quality1.5 T MRI with the radiation beam on. No degradation of the performance ofeither system was found. The integrated 1.5 T MRI system and radiotherapyaccelerator allowsimultaneous irradiation andMRimaging. The full diagnosticimaging capacities of the MRI can be used; dedicated sequences for MRIguidedradiotherapy treatments will be developed.

Company claims new cell phone chip neutralizes radiation
2009-02-08 08:26:00 A Belgian health products distributor plans to introduce a new stick-on cell phone chip that somehow counters the effects of heat and radiation in cell phones that some studies say could cause cancer.The company, called Omega Pharma, will start selling its E-waves phone chip in pharmacies throughout Belgium starting tomorrow, and will eventually make the product available in other countries.The launch is being sold in a sea of unanswered questions, including the following:1. Do cell phones really cause cancer? In the past 20 years, we've gone from nobody using cell phones to everybody using them. Where's the brain-cancer epidemic?2. Is this new chip yet another quack fix designed only to profit from public fears about cell phones? 3. Will anyone else besides the company test this product? 4. Is the chip itself safe? How does it work? Why should we trust it? If this thing sells, which it might, what does that say about public fears about cell phones? What should the handset make...

Different types of radiation
2008-06-03 06:36:00 The spectrum is divided into different groups according to the frequency of these energy waves. This is measured in Hertz, and represents how many waves arrive in a second. The higher the frequency, the more waves per second. Mobile phone frequencies are actually right on the border between radio waves and microwaves, so their emissions are sometimes referred to as microwaves. Different types of radiation All parts of the electromagnetic spectrum are described as 'radiation', but not all radiation is the same. At the top of the scale, ionizing radiation (as in radioactive decay or X-rays) has the ability to alter matter, including human cells. It has very high energy which can change a molecule's structure. This can have serious consequences - ionizing radiation can cause changes in the structure of DNA, leading to mutations and in some cases cancer. By contrast radio waves, such as in mobile phones, are at the other end of the spectrum. They have very low energies,...

Mobile phone radiation and health
2008-06-02 06:33:00 Mobile phone radiation and health concerns have been raised, especially following the enormous increase in the use of wireless mobile telephony throughout the world (as of August 2005, there were more than 2 billion users worldwide). This is because mobile phones use electromagnetic radiation in the microwave range. These concerns have induced a large body of research (both epidemiological and experimental, in non-human animals as well as in humans). Concerns about effects on health have also been raised regarding other digital wireless systems, such as data communication networks. The World Health Organization, based upon the consensus view of the scientific and medical communities, that serious health effects (e.g. cancer) are very unlikely to be caused by cellular phones or their base stations, and expects to make recommendations about mobile phones in 2009–10. However, some national radiation advisory authorities, including those of Austria, France, Germany, and Sweden rec...

Crohn's Disease Patients Should Limit Their Exposure to Radiation!
2008-05-06 19:13:00 Specialist centres must take steps to reduce the amount of radiation people with Crohn's disease are exposed to from diagnostic imaging, radiologists have urged [1]. Patients with Crohn's disease may be particularly vulnerable to radiation owing to their young age at presentation and an elevated risk of some intestinal malignancies such as small bowel lymphoma.Researchers estimated the cumulative effective dose (CED) of diagnostic radiation of 354 patients with Crohn’s disease treated at a tertiary centre.They found that 55 patients, 15.5 per cent, had a 'high' CED – defined as greater than 75mSv.Less than six imaging studies were performed per patient over the first five years of the 15-year study. During this period the mean CED was 7.9mSv, with CT accounting for 46.3 per cent of radiation exposure.During the last five years, these figures had increased to almost seven images per patient and a mean CED of 25.1mSv. CT accounted for 84.7 per cent of radiation exposure at thi...

Drug to block Radiation damage
2008-04-11 18:30:00 A new drug may protect healthy tissue during exposure to radiation. Molecular geneticist Andrei Gudkov and colleagues report in Science this week that they protected mice from the cell-damaging effects of radiation by injecting them with a compound that helps cells resist apoptosis, or self-destruction. Known as CBLB502, this compound switches on a biological mechanism that helps healthy cells survive blasts of radiation.Studies in animals suggest CBLB502 protects healthy cells in the bone marrow and digestive tract against radiation but does not seem to protect tumour cells which remain vulnerable to treatment.Mice and monkeys injected with the drug between 45 minutes and 24 hours before being subjected to normally lethal radiation were more likely to survive or live longer than untreated animals, the researchers found.The researchers found that the drug only worked if injected within an hour prior to exposure to high levels of radiation. It also showed some protective effects if i...
