Air kerma: Energy released by radiation, measured per unit mass

Maximum Air Kerma Rates--The following maximum air kerma rates apply to radioscopic equipment except during recording of radioscopic images:

c) uniformity of the air kerma rate within a cross-sectional area of the radiation beam;

a) time-dependent behaviour of the air kerma rate of the pulse;

where X1 and X2 are average air kermas (exposures) per current time product.

where X1 and X2 are average air kermas (exposures) per current time product.

Following the lead of the International Electrotechnical Commission, the air kerma (in gray, Gy) replaces the exposure (in roentgen, R) as the measure of exposure.

The leakage radiation from the X-ray equipment is assumed to be an air kerma of 0.876 mGy h-1.

Following the lead of the International Electrotechnical Commission, the AIRKERMA (in GRAYS) replaces the EXPOSURE (in ROENTGENS) as the measure of irradiation.

Table to Subsection 28(1) Maximum Air Kerma or Exposure Rate of Radioscopic Equipment, Other Than When It Is Recording Images

Following the lead of the International Electrotechnical Commission, the air kerma (in gray, Gy) replaces the exposure (in roentgen, R) as the measure of exposure.

Following the lead of the International Electrotechnical Commission, the AIR KERMA (in GRAYS) replaces the EXPOSURE (in ROENTGENS) as the measure of irradiation.

Following the lead of the International Electrotechnical Commission, the AIR KERMA (in GRAYS) replaces the EXPOSURE (in ROENTGENS) as the measure of irradiation.

Some specifications may also be applicable for much shorter pulses; one example is the air kerma of one pulse.

The coefficient of variation for both air kerma and mAs shall not exceed 0.05.
