Composite of silver halide photographic light-sensitive material and radiation fluorescent screen |
摘要 |
A composite for radiography is disclosed which essentially consists of a) a silver halide photographic light-sensitive material comprising a transparent support and at least one light-sensitive silver halide emulsion layer provided on each side of the support, b) fluorescent screen A having a 80 kVp X-ray energy absorption of 40% or more and c) fluorescent screen B having a 80 kVp X-ray energy absorption of 50% or more and the absorption more than fluorescent screen A, the material being sandwiched between the screens A and B in such a manner that emulsion layer A is in close contact with screen A and emulsion layer B is in close contact with screen B, wherein the slope of the straight portion in the characteristic curve of emulsion layer A is less than that of emulsion layer B and emulsion layers A and B of the silver halide photographic light-sensitive material have sensitivity on an exposed side that an exposure necessary to give a density of the minimum density +0.5 is 0.027 to 0.040 luxxsecond.
