IEEE N42.14-1978

N42.14-1978 is a Nuclear Engineering standard titled Ray Emission of Radionuclides, providing guidance for technical work involving radiation emitted by radioactive materials. It is relevant where measured emission characteristics, controlled handling, or documentation of radionuclide behavior are important. As a superseded standard, N42.14-1978 remains useful as a reference point for understanding earlier practices and terminology in radiation-related engineering, testing, and specification work.

N42.14-1978 overview

The purpose of N42.14-1978 is to define a consistent technical basis for discussing ray emission from radionuclides in a nuclear engineering context. Standards like this are commonly used to support clarity in measurement, reporting, and comparison of radiation-related data. For organizations working with legacy documentation, historical specifications, or archived test methods, the document can help preserve continuity in terminology and expected technical treatment of emission characteristics.

Typical use cases

This standard may be consulted in laboratory environments, nuclear engineering documentation, and controlled radiation measurement workflows where ray emission from radionuclides must be described consistently. It can be relevant to instrument specifications, calibration records, sample characterization, and technical reports that reference radioactive emissions. N42.14-1978 may also support review of older procurement documents or project files where a superseded nuclear standard still forms part of the engineering record.

Why this standard matters

Even when superseded, N42.14-1978 can matter because it helps reduce ambiguity in technical communication about radionuclide emission. Clear standardization supports safer handling, more consistent measurement practice, and better comparison of results across teams or time periods. In nuclear engineering, where documentation accuracy affects compliance, testing, and risk control, having a defined reference can be valuable for maintaining traceability and understanding legacy requirements.
