Durin; the first 2 years (1954-55) Kabelle Island samples
- were 2-3 times as radioactive as those from Rongelap Island. _ The
195€ Recwing series raised the July 3956 values of the Rongelap
Island region above those of Kabelle, but by July 2957 Rongelap
values declined to a level far below Kabelle, only to exceed (although not significantly) Kabeile again in March 1958. “By August :
of 1353 Rongelap was s$iid significantly higher than. Kabelle.
The
fallout from the Hardtack series is reflected tn the higher levels
of activity in August, than in Mareh 1958.
