Simple Decay Equation – Example (Polonium 210)

Tagged as , , , , , , , ,

How to calculate the current activity of a source given the activity at one point, the time which has elapsed, and the decay constant.

Activity_now = Activity_then * e^-((ln2/halflife)*elapsed_time)

Now, enter into your calculator for activity of 1000Bq, halflife of 20min, and elapsed time of 40min:

1000 * e ^ – ( ( ln(2) / 20 ) * 40 ) )

A nice little unit, the UCS30 comes with 512, 1024, 2048, or 4096 channels. The unit has a built-in high voltage source and a pre-amplifier.

There are many great and wonderful scientific devices which we can obtain and use to understand our world. The most important things we can do in our lives are to learn all that we can and teach as much as possible to all who will listen.

The unit can be seen at http://spectrumtechniques.com/

Oh… and no, they didn’t ask or pay me to show off their unit. Unfortunately, I had to buy the unit myself 🙂

Autunite Uranium under long wave UV light

My samples of Uranium taken under a microscope were recently published in the September 2012 edition of Microbe Hunter magazine! Don’t forget to check out my previous published work in the same magazine, Microscopy Meets Gamma Spectroscopy – Modern Day Alchemy
