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.
Whilst dosimetry in its original sense is the measurement of the absorbed dose delivered by ionizing radiation, the term is better known as a scientific sub-specialty in the fields of health physics and medical physics, where it is the calculation and assessment of the radiation dose received by the human body.
