Sv/s
The measurement unit for equivalent dose rate is:
Sv/s
Gy/s

The absorbed dose of a photonic radiation:
is directly proportional to the exposure X
is inversely proportional to the exposure X
does not depend on exposure X.
The energy deposited by the ionising radiation per unit mass of the medium is called:
absorbed dose
equivalent dose
exposure.
The total charge of the ions of one polarity, produced by the radiation in unit mass of air, is called:
exposure
absorbed dose
equivalent dose
The exposure:
is directly proportional to the total charge of the ions of one polarity;
is inversely proportional to the total charge of the ions of one polarity
does not depend on the total charge of the ions of one polarity.
Radiometers measure:
the activity of radioactive sources;
doses
exposure
The biological effect:
increases with the equivalent dose rate
decreases with the equivalent dose rate
does not depend on the equivalent dose rate
The biological effect…………………with the absorbed dose rate.

Semiconductor detectors are used to measure:
the energy distribution
the wavelengths
the velocity
