• Resumen

  • Using a Geiger–Müller tube, sound-capturing software, and a simple computer program, students measured to reasonable precision the half-value layer of steel in absorbing high-energy gamma rays from a Radium Ore Revigator (pronounced re-vig-a-tor with the accent on “vig”), an early quack medical device. This article describes the process used for conducting online radiation exposure experiments as part of an in-class Course-Based Undergraduate Research Experience (CURE) project, with their instructor acting in a more subservient role carrying out actions requested by the students. The manner in which this student-centered approach can drive similar online radiation experiments without compromising student safety is discussed
