The principle of fractionation refers to the relationship between:

As a radiation worker, your annual equivalent dose limit to your hand is:

Therapeutic ratio:

The SI units for equivalent dose are:

If a high school student wanted to do an unpaid internship in a radiology department, their dose limit would be:

Accelerated fractionation is: effective on all types of tumors useful in reducing the potential for tumor cell repopulation useful in reducing the potential late effects useful in reducing the acute toxicity of normal tissue

A pregnant radiation worker should:

In radiation therapy, failure of local control can occur due to: Error in patient setup Excessive margins on tumor volume Non-uniform irradiation of the tumor Error in localization

In the US, the average annual radiation exposure from medical imaging procedures is now ____________ exposure from natural background radiation.

All of the following are true regarding advantages of Linear Quadratic equation over the Nominal Standard Dose EXCEPT.
