ROUNDING APPLIED TO INVESTIGATION AND SCREENING LEVELS

Tables 1A (HILs and interim HILs)

 Rounded to 1 or 2 significant figures (see Schedule B7 Appendix C for details)

Tables 1A (HSLs) and 1B (EILs and ESLs) rounding rules

 < 1   to nearest 0.1

 1<10   to nearest whole number

 1< 100   to nearest 5

 100<1,000 to nearest 10

 1,000<10,000 to nearest 100

 ≥10,000   to nearest 1,000

Numbers ending in '5' are rounded up, for example:

 0.05 rounded to 0.1

 1.5 rounded to 2

 115 rounded to 120
