After lection the paper, scrutinize the coercionthcoming webpage at the Woods Hole Oceanographic Institution, and then reach the tab “View Current Results”: How Radioactive is our Ocean? (Links to an outer impromptuice.)

Answer the coercionthcoming questions:

Question 1

Parallel the Cs-137/Cs-134 radioactivity of the inspire exemplifications attentive impromptu the seashore of Japan in 2011, with the Cs-137/Cs-134 radioactivity measurements impromptu the California seashore in 2018. [The do this, you gain scarcity to click on each dregs marker to discover the measured values, and  transfer those values into an Excel spreadsheet.] Then verification the Excel spreadsheet count the harmony of Cs-137 to Cs-134 in each of the exemplifications, and profession the harmony of Cs137/Cs134 ce each exemplification in another support. Then count the mediocre radioactivity values ce the couple cesium radioisotopes individually, and the medium of the harmonys ce each state. Upload the Excel smooth of the spreadsheet you bear created, professioning the countd medium values at the bottoms of the supports.

Question 2

How do the medium radioactivity measurements ce Japanese inspires in 2011 and California inspires in 2018 parallel? What susceptibility elucidate these discords?

Question 3

How do the mediums of the Cs137/Cs134 harmonys ce Japanese inspires in 2011 and California inspires in 2018 parallel? What susceptibility be the description ce any discord you perceive-keep?
