In modern day baseball, teams generally have five starting pitchers, and they take it in turn to start a game every fifth day (hence the phrase rotation). Sometimes, if the schedule pans out, a team can get away with a four man rotation, and in the distant past some teams managed a three man rotation.
How Do Dosimeters Work? Dosimeters measure prolonged exposure to potentially dangerous effects. They are used by workers and scientists in a variety of situations, but the most common dosimeters measure either ionizing radiation or noise over periods of time.
Thermoluminescent dosimeters (TLDs) More sensitive than film badges Some can measure readings lower than film badges Use lithium fluoride crystals to record radiation exposure Not sensitive to heat and humidity Available for use on torso and finger Thermoluminescent dosimeters
