1.1 This test method is for determining the maximum x-ray sensitivity coefficient (slope of diffuse visual density versus x-ray exposure) of film/processing combinations for low quantities of x-ray exposure to silver halide photographic film. This coefficient can be used to assess the relative susceptibility of films to damage from x-ray exposure, such as that encountered in airport and similar security screening systems. 1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice covers the calibration of photographic emulsions and their use in measuring spectral line intensity ratios. Several methods of external illumination are outlined. Instructions are given for using regression in a computer program for defining the emulsion calibration from preliminary curves prepared by using the two-step and two-line methods and the in-line group procedure. Correction for spectral background is discussed in some detail, and instructions are given for preparing analytical curves. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
