Human external exposure and a risk to inhale radioactive substances are attributed to the early phase of a nuclear and radiological accident.

Moreover, carrying out an examination by sampling practices appear to be quite a time-consuming, inconvenient and sometimes even unacceptable procedure as the sample collection might cause damage to the integrity of a product (or packaging).

Depending on a state and density of tested food, information about radiation is transferred to the attached detector from the food with the volume of ~50÷250 l. If performing the same number of measurements by placing the detector as that of taking samples by a traditional method, one will get much more reliable integrated image of large volumes of food as there is a sort of direct data communication with the substantially larger volume of tested object.

The experienced users with its help can visually control (observe) typical display of cesium radiation in the spectrum or control potential abnormalities of background radiation.
  • Page 35 2.3 Ideally, the band should gradually and symmetrically move towards a conditional central line in horizontal direction (examples are shown in Figure 2.13). If the band behaves that way during measurement (we can see that band edges are more or less symmetric with respect to the horizontal center shown with a red line-cursor), it means that the current result of specific activity calculation is valid enough.
  • Page 36 2.4 In reality, the band almost always behaves in a different way. If the band during measurement clearly deviates from a horizontal direction (moves up or down), it means that spectrum balancing processes are not steady yet (Figure 2.14 illustrates some examples of the unstable band). In order to get more reliable measurement results you should wait until the band begins moving in a stable horizontal direction (Figure 2.15 illustrates the examples of a gradual change for a stable measurement mode).
  • Page 37 Figure 2.15 – Stable trend band 2.5 A bandwidth is another important feature apart from its shape and direction, since it displays the error in measurement. Considering the level of accuracy you want to obtain, please wait until the band reaches an acceptable width.
  • Page 38 Figure 2.16 – Evaluating the width of the trend band 2.6 The line-cursor can also be used to control the bandwidth. By placing the cursor at the level of the right end of the band’s upper edge, and then shifting it to the lower edge (see Figure 2.17), we can observe a numeric value, which corresponds to the level of a cursor position.
  • Page 39 2.7 The band is always much narrower and more stable when a large object is under measurement. All the figures, described in the following subsections, will be improved and reached much more quickly in such a case. 2.8 If the aim of your measurement is to make sure whether the specific activity exceeds some specified level (threshold value), the trend mode appears to be the most time-effective.
  • Page 40 2.10 If cesium is detected in the product under testing, the lower band edge will move up the line of “zero activity” (i.e. 0 Bq/kg threshold is exceeded). Moreover, for a more confident conclusion you should wait until the gap between the edge and the zero line becomes well-defined and lasting enough, and there is no apparent tendency for a repeated dropping of the lower band edge below the zero line.
  • Page 41 (a) correct cursor position (b) incorrect cursor position Figure 2.20 – Control of the current activity value with the help of the cursor 2.12 If the band shape becomes stable, i.e. its edges are coming together towards the horizontal central line in a stable and continuous manner (ideally as in Figure 2.13), one can anticipate that this very central line will later on converge with the most accurate value of the specific activity.
  • Page 42 maximum probable case that there is no cesium present. The figures will show the following value of specific activity: Bq/kg − Figure 2.21 – Cesium absence 2.13.2 If the band covers the zero line (in Figure 2.22 the red line-cursor shows the zero level, which falls within the band edges), but the band center is a bit beyond the zero line, it means either cesium is absent or there is relatively little cesium present.
  • Page 43 2.13.2 will assume increasingly accurate and “constricted” values. It is important to realize that even if the band covers the zero line at a given time, cesium might still be present. To get more specific answer you should continue measurement. The band, in this instant, will get narrower around zero, or, perhaps, around some relatively small real value of specific activity.

This section provides recommendations on measurement of specific/volume activity of radioactive cesium on the example of food. Best practices for testing of soil and timber are the same.
  • Page 50 2.5.2.2 Food shape and dimensions 1. Larger food product size deliver greater precision and shorter period of time to get measurement results. The best way to conduct measurements of products is when they are stacked in a fairly large piles or large containers – it is quite easy to put the device on a pile, or a container.
  • Page 51 Figure 2.29 – Putting single-type containers together 3 The relatively small-sized containers (up to ≈25 cm) are required to have a parallelepiped-like or cylinder-like shape. If the dimensions of the object exceed ca 25 cm in all directions, the shape of the container is of no importance. Attention: Testing of food products with the dimensions of less than 14×14×11 cm should be considered as indicative, i.e.

If the area is limited in size (for example, one of its directions does not exceed 3 m or buildings are located within a few meters), local measurement performed by positioning the detector at the height of 10 cm is recommended.
