Radiochem query in the school parking lot
So, I saw this today after dropping off PharmKid at her elementary school - a great homemade car sun visor:
Do you know the answer? Actually, first things first: do you know what the question is asking?
We'll give a little more information later. I have no idea who the teacher or parent is who has this visor - the school goes from kindergarten to 5th grade and while I think our kids are brilliant, I'm not sure they will know the answer to the question.
I'll just say for now that this visor brought me back to my radioisotopes undergraduate class at the Philadelphia College of Pharmacy and Science where the late Dr. Grafton Chase asked us to calculate the amount of radioactivity in a cargo ship full of bananas.
