The Radalert 100 is a general purpose Geiger counter that can measure alpha, beta, gamma, and X-radiation. The latest features of the Radalert 100, the upgraded version of Radalert 50, includes a utility menu and a three-second menu that helps change the default settings for a number of operation parameters.
	Its digital liquid crystal display (LCD) shows the current radiation level in milliroentgens per hour from .001 to 110 or counts per minute (cpm) from 0 to 350,000. When SI units are chosen, the LCD shows readings in microsieverts per hour from .01 to 1100 or counts per second (cps) from 0 to 3,500. This instrument also provides an accumulated total and timer function, up to 9,999,000 counts and 40 hours.
