Gamma Ray Spectrometric Analysis of Sand Samples from Selected Beaches along Kenyan Coastline

Figure 2

Average activity concentration of ²³²Th, ²³⁸U, and ⁴⁰K values measured in the sand samples from the six beaches (activity concentration of ⁴⁰K has been reduced by a power of ten for clarity of ²³⁸U and ²³²Th levels).
