Measuring laser power with a mirror and a scale

A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the force on the mirror driven by the radiation pressure of the laser light, presents a more rugged and more portable solution than current meters.Read More

MTM's RAD watch packs a built-in Geiger counter

There are few things more embarrassing than being caught in an all-out thermonuclear war and realizing that you've forgotten your Geiger counter. To prevent this social faux pas, MTM has released its Special Ops RAD watch. Available in black or silver (gray has already sold out) titanium cases, the RAD watch includes an integrated Geiger-Müller tube for measuring exposure to harmful ionizing radiation. Read More

High-Access Survey Robot begins work at TEPCO nuclear plant

The Tokyo Electric Power Company's decommissioned Fukushima Daiichi nuclear power station, damaged in the March 2011 earthquake and tsunami, is still under investigation. Progress has been slow due to lethal radiation preventing workers from accessing the site, and a lack of industrial robots ready to tackle the job. Now Honda and Japan's National Institute of Advanced Industrial Science and Technology (AIST) have unveiled a High-Access Survey robot that began work inside the reactor building last week.

New cancer radiation therapy treatment with no harmful side effects

Shortly after the discovery of the neutron in 1932, some scientists recognized the potential of boron neutron capture therapy (BNCT) as a cancer treatment. But despite decades of research, the problem of finding a delivery agent that would more effectively target the tumor without harming surrounding tissue persisted. Researchers at the University of Missouri (MU) may finally have found a solution.Read More

Gold nanoparticle could allow powerful alpha particles to join cancer fight

Gold nanoparticles have already shown promise in precisely highlighting brain tumors, “blowing up” individual diseased cells, and developing a lung cancer breath test. Now researchers have created gold nanoparticles that allow an alpha particle-emitting element to be directed to small cancer tumors. The researchers say the gold coating keeps the powerful radioactive particles in place at the cancer site so they do negligible damage to healthy organs and tissue.Read More

Berkeley develops quick blood test to ID people exposed to ionizing radiation

Industrial and medical accidents have resulted in about 3,000 cases of acute radiation syndrome with over 100 deaths over the past 60 years. Far larger numbers are possible in the future from major reactor accidents or the use of dirty bombs. In the aftermath of a major incident, the radiation dosages of victims must be sorted out quickly, so that suitable treatment can begin as soon as possible. Medical researchers at the US Lawrence Berkeley National Laboratory have now developed a simple blood test to determine the exposure of a patient to ionizing radiation, that can be carried out in the field with a hand-held analyzer.Read More

Alzheimer’s added to dangers faced by deep space astronauts

Psychiatrists involved with the early days of NASA’s space program were concerned astronauts might succumb to “space madness” as a result of experiencing prolonged periods of microgravity and claustrophobic isolation. While their fears turned out to be unfounded, a new study has found cause for concern for the mental faculties of astronauts on planned future deep space missions. The study shows that the levels of radiation an astronaut would be exposed to on a mission to Mars could cause cognitive problems and accelerate the onset of Alzheimer’s disease.Read More

New technique could make bread last two months

Bread may be the staff of life, but it doesn't keep very well. Left to its own devices, a loaf will start to go moldy in a week – a fact that costs consumers and the food industry millions of dollars each year. Now, according to the BBC, a Texas-based company have developed a process that kills spores so that a loaf of bread can stay mold-free for up to 60 days.Read More

Toshiba unveils four-legged nuclear plant inspection robot

Toshiba has unveiled a four-legged inspection robot, which will carry out work at the Fukushima Daiichi nuclear power plant, where people cannot go. The newly developed robot – simply called a Quadruped walking robot – comes equipped with a smaller wheeled robot that can be deployed to navigate hard-to-reach areas. The legged robot can negotiate stairs, uneven terrain, and is able to avoid low-lying obstacles.Read More
