Location and Equipment

It is situated into a bunker of 500 m² expressly made near to the production factory. It has been equipped with a control room, a storage area for instruments incoming from outside and three irradiation rooms:

1. X ROOM, where the following plants are located:

• constant potential X-ray generator Balteau with ceramic tube (30 – 320 kV)
• mammographic plant Philips (25 – 45 kV)

2. γ ROOM, where the following plants are located:

• irradiation plant with 1 Co60 sealed source (starting activity 2,6 TBq)
• irradiation plant with the following 5 sources:
  • Am241 (starting activity 11,1 GBq)
  • Cs137 (starting activity 0,111 GBq)
  • Cs137 (starting activity 1,85 GBq)
  • Cs137 (starting activity 37 GBq)
  • Co60 (starting activity 3,7 GBq)

Besides the a.m. plants, the centre is equipped with the following devices necessary for the calibration of:

Passive dosimeters — The centre is provided with a set of water phantoms (ISO phantoms SLAB, ROD and PILLAR) for the irradiation of passive dosimeters for body and limbs at prefixed doses in terms of Hp (10, a) and Hp (0.07, a), expressly made by COMECER up to the ISO 4037-3 rules.

3. α β γ ROOM, where are calibrated instruments for non Accredia report.
