    The instrument under test is viewed by a CCTV system. The facilities provide highly collimated radiation beams to minimise any effects due to environmentally scattered radiation. Gamma sources: Cs, 60 Co, Am and Ra. Instrument Calibration Service Now a Trescal Company. Instrument Calibration Service is excited to officially join the Trescal team! Our philosophy on equipment calibration has not changed. We perform instrument calibration service the correct way, never compromising integrity or quality of service. The measurement of ionizing radiation is sometimes expressed as being a rate of counts per unit time as registered by a radiation monitoring instrument, for which counts per minute (cpm) and counts per second (cps) are commonly used quantities.. Count rate measurements are associated with the detection of particles, such as alpha particles and beta particles. To understand how to protect soldiers from ionizing radiation,55Throughout this report, the term radiation refers to ionizing radiation and does not include nonionizing radiation sources, such as lasers and radiofrequency generators. it is necessary to understand its characteristics, how it interacts with tissues in the body, and the effects these interactions may have on immediate and long Author: J. Christopher Johnson, Susan Thaul.

A radioactive source is a known quantity of a radionuclide which emits ionizing radiation; typically one or more of the radiation types gamma rays, alpha particles, beta particles, and neutron radiation. Sources can be used for irradiation, where the radiation performs a significant ionising function on a target material, or as a radiation metrology source, which is used for the calibration.
