Russell Fraser Sales has unveiled its range of personal radiation detectors.
This range includes the Roffey PRDIII, Graetz GammaSmart, GammaTwin, and Survey metres
The Roffey PRDIII and Graetz GammaSmart personal radiation bleepers provide an automatic audible and visual warning of the presence of ionising radiation.
The alarm is a high-pitched bleep with a repetition rate proportional to the radiation intensity.
The visual alarm is a bright flashing LED that is visible to the wearer, and other people working in the same area- this is particularly useful in areas of high background noise such as minesites.
The GammaTwin dose rate meter measures the ambient dose equivalent rate and is used for the measurement of gamma radiation and x-rays.
Featuring the energy compensated Geiger-Muller-tube detector, and a large LCD display, the GammaTwin automatically and continuously stores the accumulated dose.
It offers simultaneous or separate indication of dose and dose rate and quasi-analog indication of dose rate (logarithmic bar graph).
It also features 4 preset dose rate alarm thresholds and 4 preset dose alarm thresholds.
The Graetz X5Cplus Radiation Survey Meter is a PTB-approved doserate meter for measuring gamma radiation and X-rays.
Utilising an energy compensated Geiger-Müller-tube and a large digital indication of measured values on the illuminable LCD display, the Graetz X5C radiation survey meter offers additional settings such as alternative indication of doserate or dose with integration time; quasi-analog doserate indication (3,5 decades, logarithmic bar graph); indication of peak and average value of doserate; 4 available programmable dose and doserate alarm thresholds; automatic or manual storage of dose and doserate values together with date and time and indication of residual time for staying in the current radiation field with regard to the maximum allowed dose.
The X5C is IP67 rated and is sealed for submersion up to 1m depth.
The X5CEx is intrinsically safe for operating in explosive environments.
The majority of the units are IP54 (splash proof) and designed for a robust environment.
