It must be noted that dose tolerance limits and dose-volume histogram (DVH) analysis only show part of the overall situation. The location where the high dose occurred could sometimes be more important than how high the dose is.t must be noted that dose tolerance limits and dose-volume histogram (DVH) analysis only show part of the overall situation.

Hi Kent. Exponential form simply means a numeric form involving exponents. One way to write such a number is by recognizing that each position represents a power (exponent) of 10. So you can first break it up into separate pieces.
Exponential decay: the change that occurs when an original amount is reduced by a consistent rate over a period of time. Here's an exponential decay function: y = a(1 -b)x. 1  y: Final amount remaining after the decay over a period of time.2  a: The original amount. 3  x: Time. 4  The decay factor is (1- b). 5  The variable, b, is percent decrease in decimal form.xponential decay: the change that occurs when an original amount is reduced by a consistent rate over a period of time.
