Recently, two scientific papers have reported positive detection of nuclear radiation from similar electrochemical cells operating with deuterated water. We have experimented with similar electrolytic cells and have looked for energetic charged particles which are characteristic of nuclear fusion reactions. We report on six variations of the cell, with an upper limit of 0.005 detected particles/${\mathrm{cm}}^3$ sec. Within background statistics, we observe no nuclear fusions.
