This is the first episode in awhile. I have been working on other aspects of LearningMeasure.com in the last several months. This episode is on ionizing radiation, and is the result of a request from one of you.

This episode concerns with the units used to measure ionizing radiation, namely units of decay rate, ioniziation rate, absorbed dose, and equivalent absorbed dose.

The units described are the becquerel, curie, roentgen, grey, rem, sievert, and rad. Also described are the concepts of time constant and half life.

Many of the new features we have implemented and are planning are discussed. As always if you have a suggestion for an episode, or for LearningMeasure.com, email me at [email protected].
