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.
A noise dosimeter consists of a microphone on a cable, which can be clipped to a lapel or collar. The microphone cable is then passed under the clothing to the unit itself, which is small enough to. be located in a pocket or clipped to a belt. The dosimeter can then be started at the beginning of. the shift.
