  • Page 20 For measuring natural background levels, take the unit to the area where actual sample measurements are to be done. Make sure there are no samples close by. (at least a few meters away). Hold at least 1 meter above the ground level and 1 metre away from side walls observe the natural background (BG) reading. Make about three measurements & take average of the three readings & that should be treated as the natural B.G. (Base value) We recommend that measurement is done in nSv/hr which is internationally accepted unit. Other units available in the instrument are R/hr, CPS or CPM. Samples are available in different stages of processing like raw material entry stage, intermediate processing 5.4.2 MEASUREMENT ON A SAMPLE state, finished product stage, etc. To detect contamination without missing, maximum number of measurements that are practically possible, are to be made at various stages of production. The input stage must be giventhe utmostattention sothat you do not wastetime, money and effort in processing contaminated raw material. Samples can be in various shapes and sizes. To get authentic measurements, Samples must be chosen such that they are: Sample weight : Total weight is not less than 2 kg Sample size : Area of sample must exceed front face of the detector probe in case of external probe and front face of the unit in case of internal detector probe.

    These RaC issues are important to all exporters to Europe, USA, UK & Japan. Low level contamination cases have been found to be more in the recent past. Nucleonix systems with vast design experience in the field of nuclear instrumentation have developed a package of products for the detection and measurement of RaC for this industry.
  • Page 32 A) Normally the units used in these meters globally are Sv (sivert). In India we have been using R (Roentgen). But Nucleonix Systems has been providing both these units Sv & R. Additionally meters may have CPS , CPM , modes.
  • Page 33 12Q) Can we have some conversions between Sv & R ? 1 Sv/hr = 100 R/hr 1 mSv = 100 mR/hr 1µSv = 100 µR/hr 10 nSv = 1 ?R/hr 10 µSv/hr = 1000 µR/hr = 100 mR/hr 0.1 µSv/hr = 10 µR/hr 13Q) What is Becquerel (Bq)? SI unit of activity.

  • Page 37 32Q) What is Calibration Factor: A) This is set at factory by Nucleonix when the equipment is calibrated in Radiation calibration lab. It may be from (0.75 to 1.5) depending upon the sensitivity of the detector. It is not samefor all meters. It can be different for different meters of same type.
  • Page 38 BG fall is relatively less (By 1% to 7.5%). All these case studies were undertaken by Nucleonix Systems with the interest to help the Steel Industry in identifying & tackling the radioactive contamination in their products. It is up to you to use this data for your benefit & advantage. We are not aware whether anybody else has done this kind of case study.
