For the dose-effect relationship used in radiation protection, the unit for measuring dose is:
The becquerel ?
The sievert ?
When protecting workers and the public against ionizing radiation, is it reasonable to aim at zero risk ?
Yes
No
Applying the optimization principle means ...
First complying with dose limits, then attempting to reduce exposure even further.
Optimizing individual exposure levels, with dose limits as an additional guarantee.
The current individual exposure level not to be exceeded by exposed workers is 100 mSv per five consecutive years, subject to a maximum 50 mSv in a single year. Is this figure:
A regulatory limit ?
A danger threshold ?
The system of reference monetary values for the man-sievert is:
An aid to decision-making ?
A way of reducing the cost of radiation protection ?
The reference monetary value of the man-sievert used in the optimization procedure corresponds to:
What has been spent to avoid one man-sievert.
What the undertaking is prepared to spend to avoid one man-sievert.
Is the reference monetary value of the man-sievert:
Universal ?
Variable depending on the socio-economic context ?
The cost of a radiation protection measure (e.g. installing biological shielding) to be taken into account when implementing the optimization procedure is equal to:
The cost of the biological shielding alone.
The overall cost of installing this protection.
At the end of the optimization process, if the real cost of the radiation protection measure is lower than the reasonable cost, this means that:
The measure will not be taken.
The measure will be taken.
Is the optimization principle a universal principle that applies to all types of exposure: occupational, public, and medical (doses to patients) ?
Yes
No
