IEEE N42.61-2025

This standard specifies the notation of radiation data and some non-radiation data that is streamed digitally in real-time from a radiation detection instrument to a receiving device (e.g., smartphone or tablet). ISO/IEC 8824-1 Abstract Syntax Notation One (ASN.1) is used for specifying the data to be streamed.6 The complementary ISO/IEC 8825-1 ASN.1 encoding rules are recommended for converting the data into digital binary code for streaming. The standard is intended for both lower-bandwidth transmission, corresponding to instruments that generate data on the order of kilobits per second (kbit/s), and higher-bandwidth transmission. The radiation data consist mainly of raw or unprocessed data, but other data such as precise time, dosimetric data, device parameters, and settings applicable to the further display, processing, or analysis of the data can be streamed as well. The data can be streamed wirelessly but can also be transmitted by cable. Data format for commands from the receiving device to the measurement instrument is not part of this standard. This standard does not address data format for visual data (e.g., photos, videos), for radiation imagers, or for ladar distance data. The transmission protocol is not part of the standard, although some general transmission rules recommendations are provided. The subsequent display, processing, and analysis of the radiation data on the receiving device are outside the scope of this standard. The standard does not address the transmission media, receipt, and later transmission of data to a larger and distant network or how the data will be used and processed on the receiving device.
