In the logarithmic equation what is called?

Please type the name for the following molecular formula:  CaS

What is Clarkson’s method used for?

If the percent depth dose at a depth of 5 cm using a 6 MV beam (Dmax = 1.5 cm) at an SSD of 100 cm is 77.5%, what is the percent depth dose at the same depth if the SSD is extended to 110 cm?

The buildup caps that are used when measuring exposure for higher energy beams are usually made out of lead. 

The beam quality used in deriving the TG-51 chamber calibration coefficient is Co-60. 

Percent depth dose is dependent on:

TG-51 is a protocol of which of the following?

Absorbed dose is maximum at the surface. 

Field size may be defined geometrically or dosimetrically; geometric field size typically corresponds to the field as defined by the field light while the dosimetric field size corresponds to the 50% isodose line.
