New Dielectric Material Promises Radiation Resistant Transistors, Flexible
2008-06-19 07:48:00
Roll-up, transparent computers and displays are just one of the neat sci-fi gadgets a new material from Northwestern University may lead to.DailyTech has in the past covered research into the effects of long term exposure to space bound radiation on humans. Though mankind has spent many years in space, the effects of prolonged exposure, even under ideal circumstances, are as of yet unknown. Though the human part of space travel is the most important part of the equation for manned flight, radiation poses a series threat to other participants ? especially electronics.The effects of radiation on over-the-counter electronics are, in contrast, fairly well known. One of the most important parts of any electronic appliance, the transistor, is one of the most susceptible components to radiation. The problem comes from the absorptive properties of the silicon dioxide dielectrics that insulate a transistor's gate from its semiconductor components. Silicon dioxide captures radiation, which i...
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...

Common aquatic animals show resistance to radiation
2008-04-06 21:26:00
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal species studied to date. Because free radicals such as those generated by radiation have been implicated in inflammation, cancer, and aging in higher organisms, the findings — published this week in the Proceedings of the National Academy of Sciences by Harvard’s Matthew Meselson and graduate student Eugene Gladyshev — could stimulate new lines of research into these medically important problems. “Bdelloid rotifers are far more resistant to ionizing radiation than any of the hundreds of other animal species for which radiation resistance has been examined,” says Meselson, Thomas Dudley Cabot Professor of the Natural Sciences in Harvard’s Faculty of Arts and Sciences. “The...
Should You be Concerned About the Health Impact of Cell Phone Radiation on
2008-04-06 19:40:00
Few people have not heard the many different rumors, ideas, beliefs, and "news reports" that have indicated that the radiation from cellular phones may be bad for our health. Gossip claiming health issues of all kinds, from brain tumors to birth irregularities and other claims have been related to talking on cell phones, but have you ever asked yourself if any of these stories actually have facts to go with them? If you or someone you love uses a cell phone - especially on a regular basis - then the odds are that the thought has indeed crossed your mind.The reason that so many people have heard and often believe these stories is because of the electromagnetic waves used by regular cell phones that are in the microwave range, as well as the growing number of cell phone towers popping up in residential areas and places where people commonly gather.When it comes to cell phone towers, they have been specifically designed so that the waves occur far above where people are moving about, a...
Side Effects Of Radiation Treatment For Prostate Cancer
2008-04-02 15:00:00
Radiation Treatment for Prostate Cancer: ForewarningRadiation therapy, because of its numerous side effects, is seen as the last resort treatment for prostate cancer. That is why the people usually opting for radiation therapy are also those patients who have already gone through and tried all other options, and thus making a relatively safe procedure of radiation therapy having the highest mortality rate.For all its worth, radiation therapy is the least enveloping cancer treatment. That alone speaks of the least complications.The Side Effects of Radiation Therapy on Prostate Cancer are expected. Except the risk of another cancer, it is the same with all other the treatment for prostate cancer: infertility, impotence, bowel and/ or urinary incontinence. Another danger is the damage of the epithelial surface of the skin where the radiation had hit. There is also the collateral radiation damage, this damage of the surrounding tissues where it may hit some vital organs less resilient t...

Psa Bounce After Radiation Therapy For Prostate Cancer: Keeping An Eye On T
2008-03-22 15:47:00
Prostate specific antigen (PSA) is a protein produced by the prostate gland. It is measured in the blood stream and is a useful tool for following men who have been treated for prostate cancer. Does a PSA elevation after radiation treatment, be it a prostate seed implant and/or external beam radiation therapy, always signify disease recurrence?In the past, a PSA elevation after a prostate seed implant or external beam radiation therapy was considered to be a harbinger of a prostate cancer relapse, often prompting expensive tests and invoking a great deal of patient anxiety. Then, when the PSA level climbed to10 ng/ml or greater, men were placed on hormonal therapy. Since the latter is associated with a number of unpleasant side effects, it is desirable to refrain from using hormonal therapy unless necessary. The question then arises: when does an increase in the PSA level not signify that cancer has returned? There is a phenomenon known as a PSA bounce, in which the PSA level jumps ...

Of the 83 colony worlds that dance and prance around our golden star, only six worlds (excluding our home planet) hold the potential of being future homes, nine if you include Mercury, Pluto and Charon.Despite the fact that future technology could eventually open up all of these worlds for human habitation, only a few of them may attract "the masses" after the first person sets foot upon their dusty soil due to the "evil R word"--radiation.Contrary to the various rumors, taking heavy doses of radiation does not turn one into the Hulk, one of the members of the Fantastic Four or Spider Man via a radioactive spider bite.Radiation, whether cosmic or solar has the potential of seriously roasting you alive, if not turning one into a vegetable.Even though humans can tolerate "various degrees" of radiation, our bodies seem to be quite content with the level of background radiation our species receives on planet Earth, which is about 0.35 REM's (aka Roentgen Equivalent Man) a year.Higher d...
