Unit Risk Factor = R = P/D = P/CIT

Step 1. Enter input variables:

P = risk =

I = intake =

C = concentration =

T = time of exposure = years

Step 2. Calculate time (in days):

T = time of exposure = 365 * years = days

Step 3. Complete the calculations:

R = Unit Risk Factor = P / D = P / [C I T]

R = /[**]

R =
