Description of DOSEman
The development of the radon daughter product dosimeter was initiated by the German Federal Office of Radiation Protection (BfS). The instrument is also qualified for the continuous measurement of radon progeny concentration.
In combination with a radon monitor (like RTM 1688-2), an inexpensive system for Equilibrium Factor measurements is offered.
Dimensions and weight were designed to ensure the mobility of the wearer of the radon daughter product dosimeter. The internal rechargeable battery allows an autonomous operation of more than 40 hours. Due to the optimised sampling head, no other maintenance is required than a monthly filter replacement (continuous operation at normal dust pollution).
The display of the radon daughter product dosimeter can be toggled between the “Potential Alpha Energy Exposure (PAEE)”, the equivalent dose and the actual concentration levels, PAEC as well as “Equilibrium Equivalent Radon Concentration (EEC)”. The dose calculation is based on a user defined dose conversion coefficient. If the dose value exceeds an adjustable threshold, an audible alert will be activated.
The radon daughter product dosimeter is tamper-proof. Several programmable codes are provided to assign the acquired data to a person or location later on.
The time distribution of the radon daughter product concentration is stored in a non-volatile memory and can be transferred to a PC by the infrared interface. A special infrared adapter with USB connection is required.
The radon daughter product dosimeter will be shipped with the current version of the Radon Vision software.
Applications:
• Personal dosimeter for the exact determination of exposure to short-lived
radon daughter products, for example in mining
• Continuous measurement of the radon progeny concentration
Features:
• Can operate autonomously for 48 hours
• Acoustic alarm when a definable dose limit is exceeded
• One-button operation and tamper-proof
