The goal of DD IEC/TS 61850-80-1 is to describe standardized mapping of device-oriented data models (for example IEC 61850) with already defined attributes of CDC's and services (for example IEC 61850-7) onto the already defined ASDU's and services of IEC 60870-5-104 or IEC 60870-5-101

This Part 2-2 is not applicable to external circuits and their components intended to be connected to the input terminals

Measurement of radioactivity in the environment. Air: radon-222 - Spot measurement method of the potential alpha energy concentration of its short-lived decay products Ingestion-build-83346 The aim of BS 1771-11 Scope 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. 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. The measurement method
