Michigan Nukes Expensive Cancer-Radiation SitesProton Beam Therapy"Because the technology is shiny and new..."No, it is not. Loma Linda University Medical Center has been treating many types of cancer patients since 1990. "Proton-beam treatment may be more accurate — and thus somewhat safer and more effective — than traditional...
The National Academy of Science NAS has released a report on health risks for exposure to low levels of ionizing radiation, prompting OSHA to grant stakeholders more time to comment on whether the agency should revise its decades-old regulation o The National Academy of...
Xilinx Inc., San Jose, Calif., is being awarded a $23,424,000 firm-fixed-price contract. This action provides for research and development to produce a radiation hardened by RHBD implementation of a fully functional multi-million gate single-event Xilinx Inc., San Jose, Calif., is being awarded a $23,424,000 ...
The Occupational Safety and Health Administration is asking for comments and information to help determine if it needs to change its standards for occupational exposure to ionizing radiation. Ionizing radiation has long been used in workplaces and it The Occupational Safety and Health Administration is asking...
U.S. EPA Air and Radiation Chief Jeffrey Holmstead is resigning from his position next month to spend more time with his family, he wrote in a letter last week to President George W. Bush.U.S. EPA Air and Radiation Chief Jeffrey Holmstead is resigning from his position next month to spend...
BOSTON -- Eastman Kodak Company announced the development of a new medical imaging x-ray film that will produce the same excellent image quality available today but from half the radiation dosage currently required. This new general purpose film will be the first radiographic film in 20 years to provide high-resolution...
The U.S. Postal Service is using radiation to battle anthrax, but it's unclear what impact the method will have on plastic products shipped via standard mail. Postal centers in Trenton, N.J., and Washington - centers that serve parts of Washington The U.S. Postal...
Most fibers are subject to adverse effects of time or ageing, which are facilitated by the presence of UV radiation. Fiber ageing results in structural changes in polymer and consequently affects some fiber properties. The aim of this study is to explain the effect of UV radiation under artificial exposure...
This paper discusses the barrier properties of textiles designed for clothing as a protection against UV radiation, while also taking into account the trends of current fashion. The barrier properties of model fabrics as a protection against UV radiation have been examined by measuring the UV absorbing capacity of polymers...
MINNEAPOLIS -- In a timely response to a new request for radiation countermeasures from the United States government, Humanetics Corporation said today that it has submitted a proposal to the Department of Health & Human Services HHS to provide up to 100,000 doses of BIO 300, its oral countermeasure for...
A PV laminate converts roughly 15% of the incoming radiation into electricity, but a far larger part of roughly 65% of the incoming radiation is converted into heat. In order to test if this heat can be collected and used as a source for a heat pump, a system of...
Solar radiation is converted into both heat and electricity by PVT panels. This paper discusses the basic concept of PVT panel which consists of a PV laminate that is joined with a sheet-and-tube type solar thermal absorber. Increase of the thermal absorption was the main drive for the first and...
This paper looks at the remote sensing from satellites and how it can be used to detect oil on the oceans. The sensors used are divided into two main categories, passive and active. A radiometer is a passive instrument, thus it uses radiation from an external source. Radar is an...
This white paper document reveals about the solar energy resource which is characterized as either direct beam radiation or diffuse radiation. Direct Beam radiation is received from the sun without a change in direction, whereas diffuse radiation is received after it has been changed by reflection and scattering by gasses,...
U.S. Department of Health and Human Services HHS secretary Mike Leavitt announced on March 8 the release of a new downloadable diagnostic and treatment toolkit designed for physicians providing medical care during a radiation incident. The electronic inU.S. Department of Health and Human Services HHS secretary Mike Leavitt announced on...
A sensor developed by researchers at the Department of Energy's Pacific Northwest National Laboratory PNNL can prevent patients from receiving the wrong dose of radiation. The sensor is made from glass fibers that provide real-time radiation detect A sensor developed by researchers at the Department of...
This white paper investigates the proton tolerance of fully depleted SOI MOSFETs with H-gate and regular-gate structural configurations. An anomalous kink in the back-gate linear ID-VGS characteristics of the fully-depleted SOI nFETs has been observed at high radiation doses. This kink is attributed to charged traps generated in the band...
In January, EPA's Office of Air and Radiation met with industry leaders to announce it has received funding and approval to update hearing protector testing and labeling regulations, which have been pending since 2003. Brad Witt, audiology and regulatory In January, EPA's Office of Air and Radiation met with industry...
Intensity Modulated Radiation Therapy IMRT has given one the power and control necessary to maximize radiation dose to tumors while minimizing dose to surrounding tissue. IMRT continues to be a dynamic treatment advancement, as it delivers heterogeneous doses within the tumor in order to achieve a much better treatment outcome...
