Examples of Gamma radiography in a sentence

  • The strengthening of the physical protection, with the US-DoE’s support, of the nuclear materials used in CNESTEN’s 2MW research reactor and the security of the facilities using radioactive sources for various purposes (radioisotope production, radiotherapy, Gamma radiography, collect, conditioning and interim storage of used radioactive sources).

  • Gamma radiography has been used to test concrete up to 450 mm thick for the presence of local voids in the concrete and the efficiency of the grouting of ducts in prestressed members; the presence and location of embedded metal may also be determined.

  • These accessories are the same for both X and Gamma radiography systems.

  • Gamma radiography is used frequently in construction work because no external power is required, which makes it suitable for inspection in remote areas; the cost of the equipment and source is much less than that of X-ray equipment with a comparable kilovolt range; the isotope equipment is more easily transported; the equipment is ruggedSOURCE OF X-RAYS Figure 8-6.

  • An additional factor was that X-ray radiography rather than Gamma radiography had only been used in the testing as the system had not been deployed underwater.

  • In Oldham, the Housing Strategy focuses on four key themes: • Residential growth• Healthy homes• Improving neighbourhoods• Building stronger communities This Preventing Homelessness Strategy sets out: • Our Vision• Our Challenges• What we have done to address them and• Our priorities for the next 5 years Our 5 year strategy will be reinforced by an annual delivery plan.

  • Gamma radiography devices must be provided with a visual indicator to show whether the source assembly is in the secured “beam off” position.
