RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE
AND MOBILE RF COMMUNICATIONS EQUIPMENT 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.
