Magna 1 cc



Designed Especially for Mammographic Measurements

The Magna 1cc ionisation chamber is designed especially for mammographic dose and dose rate measurements. It also has an excellent energy response and can be used for radiographic applications. The Magna Ion Chamber is the ideal choice for two reasons; Evaluations of Magna chambers show an average response is within ± 1% over an extended mammography range of 20-40 kVp (HVL of 0.15 mm to 0.73 mm Al).

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 1 cc will be delivered in a durable case for its best protection.
