Radiation Protection 2 (SE, EP)

Definition of exposure (dose)

• amount of absorbed charge at unit mass

• amount of temperature difference at unit volume

• amount of absorbed energy at unit volume

• amount of generated charge at unit mass

• amount of absorbed energy at unit mass

Definition of absorbed dose

• amount of absorbed charge at unit mass

• amount of generated charge at unit volume

• amount of absorbed energy at unit mass

• amount of generated charge at unit distance

• amount of generated energy at unit distance

The derived unit of equivalent dose

Effective dose weights for

• type of radiation AND type of tissue

• type of tissue (only)

• type of radiation (only)

• energy of radiation (only)

Equivalent dose weights for

• type of radiation AND type of tissue

• type of tissue (only)

• type of radiation (only)

• energy of radiation (only)

The order of effective range ("penetration depth") with same energy:

• gamma > beta > alpha

• alpha > beta > gamma

• alpha=beta > gamma

• gamma > beta=alpha

The decay law is

• exponential function

• linear function

• logarithmic function

• power function

The half value thickness is

• a thickness that reduce the initial intensity to its half

• a reciprocal of a thickness that reduce the initial intensity to its half

• a reciprocal of a thickness that reduce the initial intensity to its "e" part

• a thickness that reduce the initial intensity to its "e" part

Definition of dose rate

• dose at unit area

• dose at unit mass

• dose at unit time

• dose at unit area and unit time

TLD means

• ThermoLuminescent Dosimeter

• Total Linear Dose

• Thermal Lethal Dose

• Temperature Linear Dosimeter
