What does it means when the following symbol appears of Saphydose.
Battery level is low
Evacuation is required as the Saphydose measure 5 mSv/h
Maintenance is required by vendor
Beta radiation is detected
What is the proper set up procedure of the Intensimeter?
Switch on the X 50 DE; attach to the Telescope Probe; remove rubber cap; ready for use.
Switch on the X 50 DE; attach to the Telescope Probe; wait for self-test; X 50 DE automatically enters into dose rate measurement mode; ready for use.
Attach the X 50 DE to the Telescope Probe; switch on the X 50 DE; wait for self-test; X 50 DE automatically enters into dose rate measurement mode; ready for use.
Attach the X 50 DE to the Telescope Probe; switch on the X 50 DE; wait for self-test; press Toggle Button until dose rate measurement mode; ready for use.
What is the correct way to read the concentration level of a chemical on the Short Colour Metric Draeger tube?
The concentration level of the chemical detected is read off at the level of the tube after the colour change.
The concentration level of the chemical detected is read off at the level of the tube where there is no further colour change.
The concentration level of the chemical detected is read off at the level of the tube before the colour change.
The concentration level of the chemical detected is read off at the level of the tube at the start of the colour change.
Which of the following statements regarding the Intensimeter are true?
i) Press the Switch-over button to switch between Dose and Dose Rate measurement modes.
ii) Press and hold the Search button to use the un-averaged analogue reading to search for the directions of unknown radiation sources.
iii) Fully extend the Telescope Probe to maximise distance from the radiation sources.
iv) The function of the Telescope Probe is interrupted when the Switch-over button is pressed.
i, iii and iv
i & ii
ii, iii & iv
