        Introduction

        SHINVA design and manufacture of this equipment accord with the standard of IEC60601-1-1:2000 and IEC60601-2-11:1997.This specification sheet provides information for the Co-60 Therapy Unit type Fcc-8000F.

        1.0 Radiation Source

        lThe Co-60 Therapy Unit use Cobalt 60 Radiation Source, the dimention of the source is   φ23 mm×33mm

        lThe source head’s maximum source activity is not more than 8000Ci (2.96x1014Bq)

        1.1 Radioprotection system for Leakage

        lRadioprotection system is the main part of this equipment. According to the requirements of IEC60601-2-11:1997, the absorption dose ratio brought about by the stray radiation (including the radiation brought about by radiation material other than radiation source) measured at 1m away from the radiation source is less than 0.02mGy/h.

        lAt any accessible position 5cm away from the protection shield surface, the absorption dose ratio brought about by the stray radiation is less than 0.2mGy/h.
