When the Stealth Chamber is used as a reference detector in relative dosimetry, deviation in the measured PDDs at shallow depths and geometric shadowing of measured profiles may appear.

IBA Dosimetry sent an Field Safety Notice dated April 21, 2017. The letter informed the consignee of the issue and provided the following instruction: If a Stealth Chamber was used during commissioning of Linear Accelerator and Treatment Planning System, the consignee was asked to consider referenced deviations for larger field sizes (>20 x 20 cm) and higher energies (>60MV). They were also instructed to recheck the influence of the PDD deviation and insufficient clearance for 40 x 40 profile on their beam model and its clinical relevancy.
