Fig. 1

Freshly cleaved KBr (~3 × 3 × 1 mm) (a) is irradiated in a controlled atmosphere (b). X-rays penetrate a 0.25 mm polyethylene terephthalate (PET) substrate and react with air in a sealed reaction cell. Radiolitic products are generated, including NO2, which react with the KBr substrate and result in the growth of KNO3 crystals. After irradiation with 400 kGy in an Ar/air mixture, the resulting volume and morphology of KNO3 growth varies by proximity to the X-ray source (c).
