Industrial Intensifying Screens for Non-Destroing Control.

The name, conventional sign and range of application of screens are listed in Table 1

Table 1.

Screen name	Range of application of screens	Type of radiographic film, applied with screens
RENEX UPW-1	For obtaining high-quality images with the resolution similar to non-screen defectoscopy.	Optically color-blind (blue-sensitive) radiographic films.
RENEX UPW-2	For obtaining high-quality images with a significant reduction in exposure time as compared with non-screen defectoscopy.	The same one

The technical characteristics of screens are represented in table 2

Table 2.

Screen name	Gain constant as compared with non-screen filming, at least:	Transfer constant of contrast for 2 pairs lines / mm, at least:	Grain (mean square grain deflection factor), at most:
RENEX UPW-1	15	0,55	0,024
RENEX UPW-2	50	0,30	0,024

Emission spectrum of tungstate luminophor, of which screens are made, is in the full accordance with spectral speed of industrial and medical radiographic films.
The range of voltages on a tube recommended for application of screens is:
• 80-120 kV for screens RENEX UPW-1;
• 100-300 kV for screens RENEX UPW-2.
