Thickness

Classification

EXPOSURE CONDITIONS: 8 mm Copper Filtration, HLV 3.5 mm Copper (220 kv), Lead screens.

Available Packaging Formats

Sheet Film

Interleaved: Each film is supplied individually enclosed in a white folder for extra protection during handling procedures. For most sizes, the unit pack is 100 sheets provided as 2 x 50 sheets. The film can be loaded into metal or plastic cassettes or into exposure holders, with or without lead screens.

Non-Interleaved: This form of packaging is generally supplied in packs of 100 sheets, and is for use when film is to be loaded into metal or plastic cassettes, or exposure holders, with or without lead screens.

Pb Contactpak: This pack consists of a film sandwiched between two 27-micron thick lead screens sealed in a lighttight, water-resistant, flexible package. A vacuum inside the pack provides superb film/screen contact. The package is laser-scored for easy opening. The film type is identified on the package as well as embossed on the film itself. The package has a butt edge which is invaluable for accurate positioning in difficult situations where the image needs to fall right up to the edge of the pack. Product in this packaging is clean to use, is water and oil resistant and is available for exposure immediately.

READY-PACK II Film: These films are individually vacuum sealed in lighttight, water-resistant, flexible packages. The package is laser-scored for easy opening. The film type is identified on the package as well as embossed on the film itself. The package has a butt edge which is invaluable for accurate positioning in difficult situations where the image needs to fall right up to the edge of the pack.

Roll Film

READY-PACK (DR50-381): The film is supplied in a long, lighttight roll sandwiched between two yellow-black paper polyethelene layers. The rolls are of 60- or 100-metre lengths in a variety of widths. The film is provided in a dispenser box and is cut to length by the user in a darkroom. There is a double-butt edged format available in 16, 35 and 70 mm.

LEAD PACK (DR50-382): The film is supplied sandwiched between two 27-micron thick lead screens inside a long, lighttight paper and polyethelene sleeve. The rolls are 100 metres long and are cut to length by the user in a darkroom.

NIF bulk roll (DR50-359): The film is supplied on a cardboard core in rolls 150 metres long in three widths: 60 mm, 70 mm and 100 mm. The film must be loaded into a cassette in a darkroom.

Safelight Recommendations

Use a red safelight filter (i.e. KODAK 1, 1A, or 2 Safelight Filter) in a suitable safelight lamp equipped with a 15-watt bulb. Keep the film at least 4 feet (1.2 metres) from the safelight.

Note: Other safelight filters (i.e. KODAK 6B, 8, and GBX-2 Safelight Filter) which block radiation at 550nm and shorter wavelengths are also suitable for use.

Storage and Handling

Handle film carefully to avoid physical strains such as pressure, creasing, or buckling.

It is important to realize that meeting the chemical and physical requirements does not by itself ensure that records will not deteriorate. It is essential to provide proper storage conditions. ASTM E 1254 gives details of storage conditions.

Unexposed

50 to 70°F (10 to 21°C), 30 to 50% RH. Properly shield from x-rays, gamma rays, or other penetrating radiation.

Exposed

Keep cool, dry, and properly shielded from penetrating radiation. Process as soon as possible after exposure.

Processed

60 to 80°F (15 to 27°C), 30 to 50% RH.

EXPOSURE CONDITIONS: 200/220 kV, ISO/ANSI/EN Conditions, KODAK INDUSTREX Chemicals

Recommended Replenishment Rates

Washing and Drying

Washing: Follow the processor manufacturer's recommendation for wash flow rate, or adjust flow to achieve the equivalent of the wash tank capacity every five minutes, or twelve tank volumes per hour. Insufficient wash flow can adversely affect the life expectancy of processed radiographs. Wash flow rate should be increased if chemical spot tests or other analytical methods reveal a high level of retained chemicals in the processed film. For best results, the wash tank should be drained daily and left empty when not in use.

Drying: Follow the processor manufacturer's recommendation for dryer settings. In general, the dryer should be set to a temperature slightly above (3°C/5°F) the lowest temperature required to eliminate any signs of tackiness in films exiting the dryer.

Manual Processing

Notice: Observe precautionary information on product labels and on the Material Safety Data Sheets.

Develop with rack and tank, using properly replenished solutions.

Note: Remove film and hanger 5 seconds before end of development. DO NOT allow excess developer to drain back into the tank.

Stop, Fix and Wash Steps

Dry in a dust-free area at room temperature or in a suitable drying cabinet. Temperature not to exceed 120°F (50°C).

Recommended Replenishment Rates

Maintain chemical activity and solution level in the developer tank by adding 90 mL (3 fluid ounces) of replenisher according to instructions for each 14 x 17-inch (35 x 43 cm) film processed. Stir vigorously after each addition. Replenish the fixer tank at the rate of 180 mL (6 fl oz) per 35 x 43 cm (14 x 17 in) sheet of film processed.
