A radiation detector is formed from a plasma panel that includes a front substrate, and a back substrate that forms a generally parallel gap with the front substrate. The treating solution comprises water and an alkylene oxide adduct of a primary amine having a hydrocarbon group of 11 to 30 carbon atoms or of ammonia. Such a device and circuit is small, has low capacitor values, and can be used at high switching frequencies up to several hundred MHz in telephony, medical instruments, industrial processes, modems, control andor measuring apparatus, telecommunication apparatus and the like. The offer for a subsidy is from a second vendor, and may define, for example, a reduction in the price charged for the item and an obligation for the customer to fulfill in exchange for the subsidy. Subsequently to the rear edge peeling step, a front edge peeling step peels off the heat resistive base material layer from a front edge of the laminated printed object.
