What is RTR inspection?

Purpose: The purpose of this course is to provide regulatory staff with the requirements, expectations, and qualifications of inspecting research and test reactors in the United States.

What is RTR xray?

Real-time radiography is a nondestructive (NDT) method whereby invisible X-rays are used to produce digital images. The captured rays are converted to visible wavelengths of light and are used to produce real-time images. This digital radiography method is commonly used to detect corrosion in pipelines.

What is UT and RT?

The major difference between RT & UT is that Radiographic method is better for detection of discontinuities having major dimension perpendicular to the surface (parallel to the direction of radiation) and Ultrasonic method is better for detection of discontinuities orientated parallel to the surface.

What is a pipeline crawler?

General Information. Tecnitest system ‘C’ crawlers are X-ray or Gamma ray crawlers for the inspection of welded joint in pipes of internal diameter 6” to 48” (or 72” with suitable adapters). The wheel axles on the crawlers are variable and extendable to ensure centering of the unit within the pipe.

How is digital radiography used?

Digital radiography (DR) is an advanced form of x-ray inspection which produces a digital radiographic image instantly on a computer. This technique uses x-ray sensitive plates to capture data during object examination, which is immediately transferred to a computer without the use of an intermediate cassette.

What is film in radiography?

X-ray films for general radiography consist of an emulsion-gelatin containing radiation sensitive silver halide crystals, such as silver bromide or silver chloride, and a flexible, transparent, blue-tinted base.

What is an RTR in the medical field?

The “RTR” system (comprising Radiation-specific TRiage, TReatment, TRansport sites) is designed to support medical care following a nuclear incident. Medical Care sites are predetermined sites at which definitive medical care is given to those in immediate need of care.

What is a RTR 4?

The RTR-4 system is designed to help law enforcement, military, customs and security personnel search for explosives, weapons, narcotics and other contraband. The system is designed to help law enforcement, military, customs and security personnel search for explosives, weapons, narcotics and other contraband.

What is UT and MT?

Test Capabilities. Many methods are available for testing welds—magnetic particle test (MT), liquid penetrant test (PT), radiography test (RT), and the ultrasonic test (UT). MT relies on a magnetic field and steel particles; a discontinuity in the weld allows the magnetic flux to leak, attracting the particles.
