AT5350/1 Standard Dosimeter

AT5350/1 Dosimeter is a high accuracy class instrument with high functional capabilities. The dosimeter is composed of electrometer measurement unit (electrometer) and a set of ionization chambers of different volume, manufactured by PTW-Freiburg: 0.02; 0.125; 0.6; 30 and 1000 сm3.

Ionization chambers
  • TM31010 Cylindrical ionization chamber (0.125 cm3)
  • TM30010 Thimble ionization chamber (0.6 cm3)
  • TM23342 Parallel-plane X-ray chamber (0.02 cm3)
  • TM23361 Cylindrical ionization chamber (30 cm3)
  • TM32002 Spherical ionization chamber (1000 cm3)
 
Measurement
  • Air kerma rate for X radiation and gamma radiation
  • Air kerma for X radiation and gamma radiation
  • Air kerma of X-radiation and gamma radiation by numerical integration of the air kerma rate
  • Direct current rate
  • Charge
  • Charge by numerical integration of the current
 
Application
  • Ionization radiation metrology
  • Low level current and charge measurement
  • Physical research of photon radiation fields
  • Clinical dosimetry
  • Radiation therapy
 
Features
  • The dosimeter can be graduated for the following units of measure: air kerma, air absorbed dose, water absorbed dose, exposure dose, ambient equivalent dose
  • Delivered ionization chambers library is stored in the dosimeter non-volatile memory
  • Extra chambers can be added to the library          
  • Integrated high-voltage source is provided for powering the ionization chambers with output voltage setting range of ± (1-500) V with a 1 V step
  • Automatic correction of measurement results respecting the air density for unpressurized chambers according to the entered temperature and pressure values
  • Automatic compensation of spurious input current
  • Measurement units can be selected (Gy, Sv, R, A, C) according to the measured physical values
  • Mathematical and logical processing of measurement results by 8 internal resident programs
  • Up to 500 measurement results can be stored in the dosimeter memory for later review, processing and documenting
  • RS232C interface and dedicated digital inputs/outputs

АТ5350/1 Dosimeter has the pattern approval certificates of Republic of Belarus, Russian Federation, Ukraine, Lithuania and Kazakhstan.
