Dose determination of long-lived alpha and beta emitters in breathing air
The personal dosimeter MyRIAM determines the inhalation dose obtained from the exposure to long-living Alpha and Beta nuclides (LLRD) in the breathing air. The aerosols will be accumulated on the surface of a membrane filter by an internal pump. The collected activity is analyzed by a semiconductor detector with subsequent Alpha spectroscopy and Beta gross counting. The influence of natural occurring Radon daughters is fully compensated An accurate determination of the obtained dose without any additional equipment is possible by a special filter analysis mode. The small filter paper (17,5 mm diameter) can be archived and used for the preservation of evidence. The lightweight (300g) instrument can be worn on the body without impairment of mobility. The sampling head, battery, and electronics have been integrated into a rugged metal enclosure the size of a mobile phone. Therefore, no additional cables and hoses are required Dangerous doses will be detected within 60 Seconds and signalized by an acoustical and an optical alert. The display, equipped with bright back-light shows the recent dose values (μSv or mrem) as well as the overall count rates. The internal rechargeable battery allows approx.24 hours of autonomous operation – it takes only one hour to recharge the battery. No other maintenance is required other than the battery recharging and a monthly and easy to perform filter replacement. The internal data logger enables a chronological (local) assignment of the obtained dose contributions. The communication between PC and MyRIAM is realized by an infrared data link. The software for easy data analysis and archiving is included in the delivery.
Please note, that you have to order an IR adapter with this instrument. You will find them in Accessories! A battery charger is now free of charge inclusive! Other accessories are not obligatory for purchase.
