Sensitivity analysis
 

Variation in a parameter

Dose rate behind the shielding (mSv/h):
It is advisable to check how the results stand up when the quantification parameters are varied. For example, note how the reasonable cost is sensitive to variations in the dose rate behind the shielding (scroll on either side of 0.1 mSv/h).
Options Dose avoided (man-mSv)

Cost of protection
(in US$)

Reasonable cost

Without shielding 0 0 0
