A straight line is drawn in the best possible way through the three measurement points.

Then check the counting rate against a known radiation source. One o the standards in the LLW standard set is suitable or this purpose. 3. To prevent the measuring probe rom getting dirty, it is advisable to cover it with thin cling lm.

Measurement o deposit or loose material samples 1. Extract a suitable amount o material (100-200g) rom the component and place it in a container similar to the calibration containers. 2. Take the container to a site where there is no explosion risk and there are no other radiation sources nearby. 3. A unctional check o the instrument shall be perormed beore taking a measurement. Turn the instrument on rst and check the battery voltage. 4. Then check the counting rate against a known radiation source. One or the standards in the LLW standard set is suitable or this purpose. 5. To prevent the measuring probe rom getting dirty, it is advisable to cover it with thin cling lm. 6.Measurethebackgroundcountingrateonsite.Ifitislow(<5CPSyou can ignore it. 7.

This is done to nd possible other deposits o LRA that could aect the measurement. 4. Measure the background spectrum about 30 cm rom where the metering is to take place towards the area where the background spectrum (see point 3) is the strongest.

I Measurement is considered to be denitely larger than Background, the presence o LRA is proven. (Comment: it is practically impossible to defne more specifc criteria than the above. The correct use o the method depends on the users experience and good judgment.)
