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.
What does the dosimeter do? A radiation dosimeter measures the amount of high energy ionizing radiation a person has been exposed to during the wear period. These radiations include gamma radiation, x-radiation and high-energy beta radiation (such as P-32).
