Ion Chamber Magna 1 cc

Designed especially for mammographic measurements

The Magna 1cc ionization chamber is designed for mammography dose measurement. It has an excellent energy response, why it can be used for radiographic applications too. The Magna 1cc Ion Chamber is the ideal choice for two reasons;

  1. Evaluations of Magna chambers show a response within ±1% over an extended mammography range of 20-50 kVp (HVL of 0.15 mm to 0.73 mm Al).
  2. All mammographic mean glandular dose tables are based on in-air measurements.

Magna’s air equivalent construction makes it ideally suited for in air exposure measurements of mean glandular dose.

The Magna 1cc comes in a hard case for the best protection.
