The final step: making sure to put numbers in their right context. Are we looking at the whole picture? What works for some people may not work so well for others.
There is a tremendous amount of excellent technical information about radioactivity on the web, but it is often hard for anyone without that specific training to understand. There are also a lot of misleading statements and conclusions on the web. These even appear in peer-reviewed scientific journal articles such as the Chinese paper given as a link in my blog Tritium Trivia. This paper showed the results of modelling various releases of tritium water from Fukushima. Unfortunately, the last step was forgotten. Showing great expanses of red all over the Pacific Ocean would lead nearly everybody to say “How terrible! Japan is polluting the Pacific Ocean with radioactive material.” However, at the end of the document the background levels of tritium in the Pacific Ocean are quoted and this puts the release data into perspective. But nowhere in the paper was the context of the data given, that is that the levels of tritium were so low compared to normal background levels that they would be impossible to distinguish from the background variability.
I have made the decision that I will try to make my blogs as easy to read as I can so that they are suitable for most users of the web. This is not easy with technical information and my background of writing technical reports. Word has an editor function that allows you to calculate the readability of the document. Yesterday, for the very first time I managed to achieve my goal.
I was so excited that I quickly finished the blog and published it only to realize within minutes that I had forgotten a crucial step. I had jumped to the conclusion too quickly and not fully put the information into context. I rapidly edited the post and republished it. However, my subscribers received a set of comments that were not quite right. In my joy of finding a way to explain just how low tritium levels can be, I forgot just how many hydrogen atoms are in a little water. 18 g of water (one mole for the technocrats) contains 6*1023 molecules of water, 12*1023 hydrogen atoms and about a million tritium atoms. This is still just as teeny in radiation terms but the numbers 1 and a million sound so different. 1TU is only 0.118 Bq/L. I will explain what this means in future blogs.
I apologize to my subscribers. At my age you are allowed to call it a senior moment. However, I suspect that in our current haste over climate change mitigation, we are all making similar mistakes. We do the first part of the work but then forget to really look at the big picture and put everything into context.
