Q:-When considering the advantages of site RT over UT which of the following applies?

1. A permanent record produced, good for detecting defects which do not have significant depth in relation to axis of the X-ray beam and defect identification 
2. A permanent record produced, good for detecting all surface and sub-surface defects and assessing the through thickness depths of defects 
3. A permanent record produced, defect identification not so reliant on operator skill 
4. No controlled areas required on site, a permanent record produced and good for assessing the extent of pipe wall thickness reductions due to internal corrosio

Q:- One the advantages of ultrasonic inspection in relation to radiographic testing to;

A. Access is generally only required from one side (surface)of the component being tested
B. The designated work area must be closed off by barriers, therefore safety is increased
C. This materials can be easily examined
D. A permanent image of the defect can be obtained
