In biology, scientific models are…

Most of the absorbed dose in a patient is from scattered radiation.

Ethical scientific practices include all of the following EXCEPT:

MUs are ___________ when a wedge filter is used.

Calculate the gap at the skin surface for 2 fields that abut at a depth of 5 cm. using a 100 cm. The superior field size is 10 cm. x 13 cm. and the inferior field size is 9 cm. x 35 cm.

Calculate the PDD of depth (d) if the dose at Dmax is 180 cGy and the dose at (d) is 127 cGy.

A patient is treated using an isocentric AP/PA midline technique, 6 MV with the prescription for a total of a 45 Gy in 25 fractions.  The IFD is 20 cm., ES is 16 cm.2, RDR is 1.0, FSF is 1.024.   A 45-degree wedge with a factor of .580 is used on both fields which are weighted 2:1, AP/PA.  Calculate the PA MU using a TAR.

Working from home or another site is an example of a ________________ office.

I got confused about dates and missed an important deadline. I had to face the when they found out about that. 

I really regret ___________ to the Olympic Games when they were in Rio. It would have been fantastic.
