Measurements of radioactivity in the environment - Soil - Part 5 : measurement of strontium 90

<p>ISO 18589-5:2009 describes the principles for the measurement of the activity of <sup>90</sup>Sr in equilibrium with <sup>90</sup>Y and <sup>89</sup>Sr, pure beta-emitting radionuclides, in soil samples. Different chemical separation methods are presented to produce strontium and yttrium sources, the activity of which is determined using proportional counter (PC) or liquid scintillation counter (LSC). The selection of the measuring method depends on the origin of the contamination, the characteristics of the soil being analysed, the required accuracy of measurement and the resources of the available laboratories.</p> <p>These methods are used for soil monitoring following past or present, accidental or routine, liquid or gaseous discharges. It also covers the monitoring of contamination caused by global fallout.</p> <p>In the case of recent fallout immediately following a nuclear accident, the contribution of <sup>89</sup>Sr to the total amount of strontium activity is not negligible. ISO 18589-5:2009 provides the measurement method to determine the activity of <sup>90</sup>Sr in the presence of <sup>89</sup>Sr.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
