The samples of whole kelp leaf have shown some elevated activity in the channels associated with Cs-134 at 604KeV, however no secondary lines have been found and this should not be cause for concern. In an effort to confirm or deny the presence of Cs-134, the whole leaf kelp sample has been set aside and will be re-counted in several months to allow for confirmation via the half-life of the isotope in question. Previous samples of whole kelp measure over the summer will also be examined.
ケルプの葉のサンプルに、セシウム１３４のエネルギーチャンネル（604KeV)に関連するピークが見られた。しかしながら２番目の線には見られずおそらく心配はないと思われる。セシウム１３４が含まれてないことを確認するために、このケルプの葉のサンプルは保存し、半減期と関連して数ヵ月後に再度測定する。前回のケルプのサンプルも同時に調べる。
MDA: 0.035 Bq/kg
Previous samples of kelp have been recounted for comparison to the decay rate associated with Cs134 and this returned only negative results.
以前セシウム１３４の疑いのあったケルプを再度測定した結果、セシウム１３４の値はマイナス値になった。
