RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE
AND MOBILE RF COMMUNICA TIONS EQUIPM ENT AND THE X-RAY SYSTEM
(IEC 60601-1-2:2007)
This DX-D 600 Radiographic Room is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of this DX-D 600 Radiographic Room can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the DX-D 600
Radiographic Room as recommended below , according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance ’d’ in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter , where ’P’ is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer.
NOTE 1 -- At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 -- These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
