D616.131.00/10 en 

 

Intended Use 

DIADOS E  is  a  diagnostic  dosemeter  according  to 

IEC 61674 and can be used for acceptance testing 

and  constancy  checks.  It  can  be  employed  in  con-

ventional  X-ray  diagnostics,  in  dental  and  mammo-

graphic  applications  as  well  as  with  CT  systems. 

DIADOS E  is capable  of measuring dose  and  dose 

rate  in  diagnostic  X-ray  applications,  dose  length 

product  and  the  dose  length  product  rate  in  CT 

applications and current and charge if used as elec-

trometer.  DIADOS E  is  capable  of  measuring  in 

front of and behind phantoms. 

The  following  detectors  are  required  for  the  meas-

urement: 

  DIADOS  Diagnostic  Detector  T60004  for  con-

ventional diagnostic radiology and for dental im-

aging  

  DIADOS MAM Detector T60005 for mammogra-

phy  

  CT  ion  chamber  3.14 cm³  TM30009  with  CT 

adapter T16018 

  CT ion chamber 300 mm long TM30017 with CT 

adapter T16018 

 

Note: 

In  the  United  States,  federal  law  restricts 

this device to sale by or on the order of a
