X-ray lasers in focus: A new large high-precision mirror is capable of focusing x-ray radiation to spot sizes of just a few nanometers

Radiation from x-ray lasers such as x-ray free electron lasers are of wide interest, as they will allow a large number of applications such as the study of the structure of single molecules. However, for such applications to be realized, the x-rays need to be strongly focused at the nanoscale. Researchers from the RIKEN Advanced Science Institute in Wako, collaborating with researchers from Osaka University and the Japan Synchrotron Radiation Research Institute (JASRI), have now developed a mirror suitable for this task.

Cancer Risk Of Low Dose Ionizing Radiation: New Insights From Modern Biology Provoke More Questions And Challenges

Researchers now know more about the biological effects of low doses of ionizing radiation. A European project RISC-RAD (Radiosensitivity of Individuals and Susceptibility to Cancer induced by Ionizing Radiation) that started in January 2004, has carried out research to contribute to the improvement of the management of health risks attributable to low dose exposures, i.e. 100 mSv or less.

Radiation Detectors' Value Is Questioned

Officials at the Department of Homeland Security have overstated the performance of costly new radiation detectors designed to prevent the importation of radiological materials that could be used in bombs, according to an unreleased government report.

Cost of Radiation Detectors Questioned

The Washington Post reported last week that a government assessment of expensive new radiation detectors has found that the statistical evidence doesn't back up claims that they are better than existing technology at identifying radioactive materials that could be used in bombs.

RAD-30P Radiation/Metal Detector Gains Major Interest at IACP

PRNewswire-FirstCall/ -- Paradigm Tactical Products Inc. (PDGT), a leading provider of detection technology and homeland security solutions to the military as well as to the corrections, law enforcement and security industry reports that its RAD-30P Radiation/Metal wand was well received at the 2008 International Chiefs of Police conference.

NASA Looking for Radiation Hardened GPS Receivers

NASA is looking to gather more information from commercial vendors about who can provide radiation hardened GPS receivers for an in-flight fast satellite signal acquisition experiment aboard a future space shuttle flight, according to NASA's Johnson Space Center in Houston.

The European Synchrotron radiation facility launches an ambitious Upgrade Programme

More than ten thousand scientists across Europe will profit from new investments in the European Synchrotron Radiation Facility (ESRF) approved today. Over the next seven years, unique new experimental facilities for research with X-rays will come into operation. This decision, taken by the ESRF Council, representing the 19 countries financing the ESRF, confirms Europe’s vision to expand its global leadership in photon science.

Force-field minimizes space radiation danger

A simple, portable magnetic field generator inside a spaceship should be sufficient to deflect the dangerous highly charged particles of the solar wind away from a spacecraft and the astronauts inside, according to research in Plasma Physics and Controlled Fusion.

Mysterious source of high-energy cosmic radiation discovered

During 10 years, five high-energy cosmic rays (plotted as orange asterisks) came from one small part of the sky near the star Merak in the Big Dipper. Astrophysicists suspect their source is a merging pair of galaxy clusters (blue). Progressively more distant galaxy clusters appear in light blue, green, and red, while the gray shading shows the positional error for each of the five cosmic-ray detections. G. R. Farrar/A. A.
