Great Moments In Teaching – Fecal Samples

PLEASE NOTE: there is a very good reason there are no pictures associated with this story.

As some of you may know, I teach radiation safety course at a local community college. A while back, we were discussing bioassay techniques (read: ways determine if there’s been an uptake of radioactive material in the body, where, how, and how much) in my radiation safety class. 

My fellow instructor, after explaining how fecal dosimetry techniques work, declared that no one, not the subject providing the sample, not the dosimetrist who has to process it, certainly not the rest of the lab staff, nor even the lab building’s neighbors, likes it when you have to do fecal samples.

I begged to disagree before the class. I clearly remembered an occasion that a world renowned health physicist and internal dosimetrist loudly declared in my presence “I LOVE FECAL SAMPLES!

I stared at him very hard. He saw me staring. There was then a several beat pause…

He then corrected himself, declaring somewhat less loudly, “I love the numbers I get from fecal samples.”

Once again, I love making sure lessons hit home and stick for life with memorable vignettes like this to hang the information on. I’m proud to declare all our students aced that part of the exam. I’m just sad no one took video of my “Rubbin’ My Ass On Uranium” dance to demonstrate proper dosimeter badge usage.
