San Jose, California-based Cornerstone Technology has launched its low radiation DualPage display in the US and Canada. DualPage has been certified by SEMKO for distribution in Sweden since January 1990, and SEMKO, as defined by Swedish regulatory agencies, is currently the world’s most stringent standard governing electro-magnetic emissions from cathode ray tube monitors. The electromagnetic spectrum emits several types of radio waves that range from short X-rays to the longest ones on the spectrum, very-low-frequency. It is these nasties that are given off by display monitors and innocuous household items like television sets. The SEMKO standard designates a mandatory and a recommended value in the three areas of induction, magnetic field and surface static electricity, and it recommends that the maximum induction and magentic field values are 25mT/s and 50nT respectively, and static electricity ought to be less than 0.5KV. Dualpage comes in at 15mT/s and 14Nt, and it also conforms to the static electricity limit of less than 0.5KV. DualPage is modified to meet low radiation standards through the addition of an anti-static panel bonded on the display screen and a specially designed protective coil which fits around the yoke of the cathode ray tube. The anti-static panel reduces the surface electrostatic field and the coil shields the magnetic field. Dualpage costs $2,500 and the option is $150.
