The Fukushima Daiichi nuclear power plant\u2026 released an enormous amount of liquid waste of 129I<\/strong> and other fission isotopes directly into the Pacific Ocean that were subsequently dispersed eastwards<\/strong>. This paper reports on the determination of the nuclear plume impact on the West Coast of the USA that happened during April\u2013July 2013<\/strong>\u2026 The determined maximum 129I concentration <\/strong> 129I concentrations were measured\u2026 from the ocean water of the West Coast of the USA [at] La Jolla, San Diego\u2026 This work reports two sudden increases of the 129I\/127I isotopic concentration in the ocean water<\/strong>, which were observed at the end of spring 2013\u2026<\/p>\n Our exploratory measurements on the USA West Coast started on samples collected at the beginning of 2013. The lowest 129I concentrations that we measured had values between [6-20 million<\/strong>] atoms per L. Such values correspond to the equilibrium concentration of iodine\u2026 offshore of La Jolla, San Diego\u2026<\/p>\n Our results\u2026 measured offshore of Cove La Jolla, San Diego, USA, during the spring of 2013, are presented in Fig. 5. Two high and distinct spike maxima are visible<\/strong>. They reveal the maximum concentration values of [1.2 billion] atoms per L<\/strong> measured on May 24, 2013 and [1.7 billion] atoms per L<\/strong> measured on June 18, 2013, with 24 days in between. Both peaks occurred in the measurement spectrum after a slow increase in concentration Samples collected [by Fukushima Daiichi, Jun 2011] at a distance of about 40 km away from the coast [had] a maximum concentration value of [620 million] atoms per L<\/strong> for 129I in the surface water of the ocean. Taking into account this value as a reference value, the maximum 129-iodine concentration reaching the USA West Coast was 2.5 times stronger than in the contaminated ocean water offshore of Fukushima after the accident<\/strong>. If we compare it to the equilibrium value of 129I concentration in the ocean water [near San Diego], then during the impact its concentration was about 100 times higher<\/strong>\u2026<\/p>\n AMS measurements of 129I were performed on ocean water\u2026 offshore of Cove La Jolla, San Diego, USA, and definitely have shown an increase of the radioactivity more than two orders of magnitude over the natural level of the Pacific Ocean before the accident<\/strong>\u2026<\/p>\n Read study for free here<\/a> ($50 at Royal Society of Chemistry)<\/em><\/p>\n![\"\"](\"http:\/\/enenews.com\/wp-content\/uploads\/2017\/01\/lajollasamples2013.jpg\" "\\"\\"")
