Do not exit. Amber Light Trouble/Malfunction Call ext. 5000 or 5555 Buzzer Green Light Do NOT enter if there is NO green Normal Operations No Sound light. Call ext. 5000. The Radiation Alarm Monitoring System (RAMS) is the whole system that continuously monitors air. The RAMS system consists of the computer, data, Continuous Air Monitors (CAMs), and the Evacuation Alarm Unit (EAUs). CAMs are used to monitor alpha and tritium while the EAUs are the lights. Workers are trained to evacuate within 5 minutes in the event of an accident involving radioactive material. In the event an accident with radioactive material occurs and there is no alarm, personnel should evacuate in 5 minutes or less. Requirements of Dosimetry Personnel Monitoring (Dosimetry) Since radiation cannot be detected with any of the human senses, special detection devices must be used. It is possible based on the job you are going to perform and the location that the use of a dosimeter may not be necessary. Persons who enter radiation areas must obtain a dosimeter prior to entry into the area. Thermoluminescent Dosimeters Thermoluminescent dosimeters (TLDs) are used to measure radiation from neutrons, gamma and x-rays, and all but very low-energy beta particles. Each dosimeter contains materials that, when exposed to radiation, will capture the type and amount of radiation to which the individual is exposed. Very sensitive instruments measure this exposure, and an dose is calculated from the data obtained. individual’s The TLD measures external occupational radiation doses and is not a shield. NOTE:
