X-RAY TELEVISION SYSTEMS CRITERIA FOR SELECTION

The article is devoted to criteria of selection of a radioscopic system from a customer.s point of view. The majority of the systems. characteristics and their correlation with the quality of the component parts are described. Exhaustive recommendations for the selection of the necessary radioscopic system, and concise ones for a high-voltage generator and an x-ray tube are given. The article includes types of image enhancement systems and their basic parameters. A purchaser can also find rough price ranges for radioscopic systems.

The application of X-ray television systems is economically justified in comparison with X-ray radiography because of the renunciation of expensive X-ray film use and significant reduction in testing time. On the domestic market there is a rather big variety of X-ray television systems from different producers.  Sometimes, it is very difficult to make a chose as all the systems are very closed by characteristics declared. Often the producer advertises the parameters in which he succeeded the best. Frequently, these parameters are not at all important for any specific task or, vice versa, the parameter which is important indeed, hides in every way, or instead of it other parameters are given that imply from it indirectly but don’t have any direct relation with it.

Modern portable x-ray units. criteria for selection

X-ray technique occupies, probably, the biggest niche in the industrial non-destructive testing. This ensures the continuous appearance of new developments. The basis for the majority of radiographic testing is the X-ray unit. Huge variety of different X-ray units is available on the market, significantly differing by many parameters. Such variety of the types of the units, their parameters and not always correct advertising can nonplus even the experts in the field of radiation methods of testing. In this article I’d like to make an attempt to tell to the readers about main types of X-ray units, their parameters and criteria, according to which the expert can select the necessary X-ray unit.
X-ray testing is carried out by X-raying of the detail under examination with fixation of the image on the X-ray film, reusable phosphorous plates or digital image detector.

UP-TO-DATE STATIONARY X-RAY UNITS OF CABLE TYPE. SELECTION CRITERIA

The X-ray technique occupies certainly the biggest niche in industrial non-destructive testing. This ensures the continuous appearance of new developments. X-ray unit is a basis for most part of X-ray examination methods. On the market there are a lot of types of X-ray units available that significantly differ from each other by many parameters.  Such variety of the types of the units, their parameters and not always correct advertising can nonplus even the experts in the field of radiation methods of testing. In this article I’d like to make an attempt to tell to the readers about main types of X-ray units, their parameters and criteria, according to which the expert can select the necessary X-ray units. I recognize that this is practically impossible to do within one article, but I would try to give maximum useful information.
