Abstract: | A measure of functionality of agricultural sower is the layout of grains sown in the soil and labelled by radioisotope a method. To determine the precise position of the grains which are sown is a figure of merite. To resolve the problem, a detection system with focusing multihole collimator was used. A probe with collimator travelled on a self-propelled carriage. The detector pulses were ratio transmited to the field isotope lab. To label the grains of cereals, cucumber and beet the isotope 99mTc obtained from Mo–Tc generator was applied. |
