How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

Tritium is usually measured by using a liquid scintillation counter. However, liquid scintillator used for measurement will be radioactive waste fluid. To solve this issue, we have developed the method of measuring tritium samples with plasma-treated plastic scintillator sheets instead of liquid scintillator (Plasma method). With the Plasma method of 2-min plasma treatment, we had obtained measurement efficiency of 48 ± 2 % for 2 min measurement of tritium except for tritiated water. On the other hand, it needed almost 6 hours to obtain constant measurement efficiency. We tried putting silica gel beads into vials to remove H2O molecules from PS sheet surface quickly. The silica gel beads worked well and we got constant measurement efficiency within 1-3 hours. Also, we tried using other kinds of PS treated with plasma to obtain higher measurement efficiencies of tritium samples.
