• In a radiograph of a weld there is an indication appearing at the end of the weldbead. It appears as a dark rounded indication with fine small tails coming from around the rounded indication giving it some what of a star-shaped appearance. This would probably be:

• A dark crescent shaped mark in the centre of a weld bead radiographic image would probably be:
• A low density image of the letter ‘B’ on a radiographic film would probably be caused by:
• A dark, irregular indication which is located adjacent to the toe of the weld would probably be:
• A straight, dark line in the centre of the film of a weld cap would probably be:
• A radiographic exposure with 3700 GBq (100 Ci) source of Ir-192 using source to film distance of 60 cm results in a radiation intensity of 0.12 Gy/h (11.8 R/h) and a radiographic density of 2.5. The intensity of radiation needed to obtain the same density when the source to film distance is changed to120 cm is:
