Have you ever sat and wondered what the radiation level is in your house? Or whether that food you're about to greedily tuck into is organic or not? Then Lapka may have been conceived with you in mind. The people behind Lapka – a set of sensors and accompanying app for the Apple iPhone – claim their product can do all of the above and more besides.  Read More

CorPath 200 allows surgeons to carry out PCI procedures without exposure to x-rays

When we think about a heart operation, it’s only natural to be concerned about the risks faced by the patient. What is overlooked is that the surgeon often faces risks in the operating theater as well. All the modern surgical paraphernalia may make cardiac medicine tremendously more advanced than it was a generation ago, but some of that equipment uses radiation that can be very dangerous to be around ... and surgeons are around it a lot. To help alleviate this, Corindus Vascular Robotics of Natick, Massachusetts, developed the CorPath 200 System. It’s a robot-assisted catheter system for unblocking arteries that allows cardiac surgeons to operate from a protective lead-lined cockpit while carrying out cardiac stent and balloon procedures.  Read More

High-radiation environments are a silicon microchip's worst nightmare and even state-of-the-art radiation-shielded circuits can fry after just a couple hours of exposure. Now engineers at the University of Utah have come up with a micro-electromechanical system that could be used to build robots and computers that are impervious to such conditions and may help us deal with high bursts of space radiation, damaged nuclear power plants or even the aftermath of a nuclear attack.  Read More

X-ray computed tomography – or CT – scanners are designed with people of an average build in mind. When obese patients require a CT scan, the additional layers of body fat will produce blurry images if the scanner’s regular settings are used. Clinicians typically address this problem by turning up the power of the scanner. Unfortunately, doing so results in overweight patients receiving higher-than-normal doses of radiation. A new computer modeling system developed at New York’s Rensselaer Polytechnic Institute, however, could help bring those levels down.  Read More

While there have been – and continue to be – numerous studies examining the effects of radiation from mobile phones on users, Yale School of Medicine researchers have looked at the possible effects on fetuses of mobile phone use by pregnant mothers. According to the study, mobile phone radiation exposure in the womb can affect the brain development of offspring and potentially lead to behavioral disorders such as hyperactivity.  Read More

In what seems to be a response to public fears about radiation levels following the Fukushima crisis, a Japanese organization called Radiation Watch has launched Pocket Geiger, a Geiger counter iPhone peripheral and accompanying app aimed at concerned individuals.  Read More

Lock up your satellites and batten down your power-lines because a Coronal Mass Ejection (CME) is headed our way. According to the National Weather Service's Space Weather Prediction Center (SWPC), it is the strongest Solar Radiation Storm since May, 2005. According to NASA, the CME is moving at almost 1,400 miles per second (2,253 km/s) and will reach the Earth's magnetosphere as early as 9 a.m. US EST on Tuesday, January 24 - give or take seven hours.  Read More

Besides surgery, chemotherapy and radiation are the foundation of modern day cancer treatment. Although effective, these therapies often have debilitating and damaging side effects. But scientists at the National Cancer Institute in Bethesda, Maryland have been experimenting with a new form of therapy using infrared light to kill cancer cells and shrink tumors without damaging healthy tissue.  Read More

The WikiSense app and some black tape turns an iPhone 4 into a radiation detector

Earlier this month, we reported on the Scosche RDTX-Pro that connects via a dock connector to turn an iPhone or iPod touch into a radiation detector. That device is set to go on sale in Japan from next month but if you’re not in Japan or just don’t want to shell out extra cash on any peripheral hardware, then the WikiSensor app might be worth a look – it won't be as accurate, but the only extra bit of kit you’ll need is some opaque black tape.  Read More

Scientists at Northwestern University, Illinois, have outlined a new method for detecting electromagnetic radiation at the high energy end of the spectrum. The work could lead to the development of a small, hand held device able to detect this "hard radiation" and has implications for the detection of radioactive materials which could potentially be employed in terrorist weapons, such as nuclear bombs or radiological dispersion devices, as well as materials employed in clandestine nuclear programs.  Read More
