Features :
RADAX DM 5000 is a Digital Handheld Radiation Dosimeter to detect Gamma and X-ray
radiation and accumulate the dose received by it or the Dose received by the operator carrying
the Dosimeter.
With RADAX DM 5000 you can:
wDetect and accumulates radiation dose received from Radio-active materials or X-rays.
wWarns personnel working in Radioactive environments about radiation dose received.
RADAX DM5000 uses a Geiger-Mueller (GM) detector tube to detect radiation. The GM tube
contains ionization gas which generates pulse of electrical current when radiations pass
through the gas and causes ionization. These electrical pulses are counted electronically. The
Dose received is displayed in milli-roentgens (mR) & Micro-Sievert(µSv). The Dosimeter
continuous to accumulate Radiation dose till it is switched off. The last reading remains in
memory even when the power is switched off. On switching on once again, the Dosimeter
starts counting from the last reading. If required, the dose can be cleared off from memory
with help of Setting switch (S).
There are only two set of switches- one is Power On-off & Enter and the other is Setting switch
(S). The display consists of two lines. First line displays the dose in mR and the second line
displays in µSv.
Technical Features :
Detector : G M Counter

Response time : 15 Sec to 20 Sec.
Operating Conditions : 0- 50®C 90% Humidity
Display : Digital - LCD - 2 lines.
Battery : 2 nos. AA size - Alkaline.
Controls : Touch Switch for Power On-Off / Function
Construction : ABS Plastic
Operation :
Press Power switch and keep pressed till display is on. Display will show reading in mR and µSv. Bring the Dose-meter near
Radioactive source with the Detector sign pointing towards the Radiation source. The Dosimeter will start displaying radiation
dose received. While detecting the radiation, the audio buzzer gives out chirping sound. At low level radiation, the frequency
of chips is low. As the radiation level increases, the chirps become more frequent. At very high radiation or very near the
source, the chirping turns in to a whistling sound. The buzzer can be switched off when required. Press the Setting switch and
keep pressed. Select option Buzzer On, Press Power/Enter switch to save the setting. To switch off Buzzer, select Buzzer Off
option. To switch off the Dosimeter, press power switch and keep pressed till Power Off sign appears.
The buzzer can be switched off if required. Press the setting switch(S), Select option Buzzer On and press Power/Enter switch
to save the setting. To switch off Buzzer, select Buzzer Off option.
To clear Dosimeter reading in memory, press Setting switch S and when Dose sign appears, press Power switch, then press
Setting switch. The dose will be cleared.
To switch off the Dosimeter, press power switch and keep pressed till Power Off sign appears.
RADAX DM5000 operates on two AA type of batteries. It is better to put long lasting alkaline batteries which will operate for
nearly 200 hours of continuous operation. Remove the batteries when Dosimeter is not used for a long period.
