The spherical chamber is designed for the measurement of ionizing radiation in radiation protection.
Superior features make the chamber suitable as standard chamber for calibration purposes. It fulfills the requirement for excellent reproducibility and long-term stability of the sensitive volume.
The spherical construction ensures a nearly uniform response to radiation from every direction.
The energy response is very flat. This is achieved by the thin layer of aluminum on the inner wall surface, which provides for an increased photoelectric yield to compensate for the absorption of soft X-rays. The outer chamber diameter is 275 mm
