Unless otherwise noted, all times given in this report are New Zealand
Standard time i.e. G.M.T, + ‘12 hours,
Radioactive fallout in rain is expressed aa:

(a)
Deposition
- millicuries per square kilometre (mCi/kw )
(b}
Concentration
-
picocuries per litre
Concentration (pCi/litre) =
(pci/litre)
deposition (mCi/km* )
rainfall (cm)
x 100
Multiply mC/om* by 2.59 to obtain mCi/sq. mile.
