New TechnologyThe technology I have chosen to discuss is portable radiological monitoring. Several new models of equipment are being marketed. One of the most recognizable and respected names in radiological monitoring is Canberra. One of Canberra's latest offerings for portable devices is the Radiagem™ 4000. The device offers the ability to monitor dose rates and contamination levels. There are a variety of probes available for use with the meter itself. The unit is waterproof and lightweight. The Radiagem™ 4000 takes radiological measurements via an internal energy-compensated Geiger Mueller detector. Through the use of various external probes, contamination levels can be quantified and readings can be recorded. Probes can be added or removed while the instrument is on. External probes can be calibrated independently of the meter. What is it for? The Canberra Portable Meter can be used to measure transferable contamination levels, establish working dose rates and carry out isotope analyses. When performing surveys of radiological areas, it is important to collect data quickly and accurately. Modern meters allow rapid measurements of transferable contamination levels. Dose rates in work areas can be established for worker protection and to identify changes in conditions. The level of radiation to which a worker has been exposed is called the dose. Radiation dose is measured in rem. The Merriam-Webster online dictionary (2010) defines rem as “the dosage of ionizing radiation that will cause the same biological effect as a roentgen of exposure to x-rays or gamma rays.” This means that early radiation researchers found a way to equate the radiation level...... middle of paper ......watching business, I hope this doesn't happen too quickly.Works cited in Canberra.
