The goods, to be irradiated, can be placed either in the cylinder of 215-mm dia located in the middle of the cage irradiation position (inner irradiation field), or around the source-cage in the irradiation room (outer irradiation field).

The distance of the horizontal plane of symmetry of the sources from the floor is 80 cm. This height makes it possible for regular pilot-scale radiation treatment of products placed in 40 × 60 × 75-cm boxes and also at larger distances from the sources. The radiation treatment of various products placed in aluminium containers (80 × 60 × 130 cm) of 0.5 m³ volume can be carried out as well. In the space near the cage radiation treatment can be performed in small size e.g. 40 × 40 × 35-cm boxes.

The high dose intensity space within the cage can be regularly used for the radiation treatment of max. 9 litre samples (Ø180×360). Owing to the relatively large volume of the irradiation chamber, up to 1.6 m height of the useful radiation field, products can be irradiated at very wide dose rates.

Operation at night or at weekends is also possible at automatic power supply by battery, without supervision.

The irradiator is equipped with devices for water purification and exhaust air filters.

The goods to be irradiated - before and after treatment - are transported into and out of the irradiation chamber through the maze manually or with the help of carriages made for this purpose.

Dosimetry

Physical dosimetry:

Calorimetry using water, graphite and polystyrene

Chemical dosimetry:

Radiochromic films (films and pieces of polymers) exposed to radiation change their colour and the absorbance (e.g. at 656.5 nm) measured can be related to dose by calibration

The ethanol-chlorobenzene dosimeter uses the hydrochloric acid formation. Dose range: 0.1 kGy – 1 MGy
