Measurement of radioactivity in the environment - Air : radon-222 - Part 3 : spot measurement method of the potential alpha energy concentration of its short-lived decay products

ISO 11665-3:2012 describes spot measurement methods for determining the activity concentration of short-lived radon-222 decay products in the air and for calculating the potential alpha energy concentration. ISO 11665-3:2012 gives indications for performing a spot measurement of the potential alpha energy concentration, after sampling at a given place for several minutes, and the conditions of use for the measuring devices.

Measurement of radioactivity in the environment - Air: radon-222 - Part 3 : spot measurement method of the potential alpha energy concentration of its short-lived decay products

<p>This document describes spot measurement methods for determining the activity concentration of short-lived radon-222 decay products in the air and for calculating the potential alpha energy concentration.</p> <p>This document gives indications for performing a spot measurement of the potential alpha energy concentration, after sampling at a given place for several minutes, and the conditions of use for the measuring devices.</p> <p>The measurement method described is applicable for a rapid assessment of the potential alpha energy concentration. The result obtained cannot be extrapolated to an annual estimate potential alpha energy concentration of short-lived radon-222 decay products. Thus, this type of measurement is not applicable for the assessment of annual exposure or for determining whether or not to mitigate citizen exposures to radon or radon decay products.</p> <p>This measurement method is applicable to air samples with potential alpha energy concentration greater than 5 nJ/m<sup>3</sup>.</p> <p>NOTE This document does not address the potential contribution of radon-220 decay products.</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.
