Rising nuclear, medical use drives demand for radioisotope identification devices

Asia-Pacific is the fastest-growing region.

Radioisotope identification devices (RIID) market is projected to grow at a CAGR of 6.9% from 2025 to 2031, reaching about $1.93b from $8.01b in 2025, according to MarketsandMarkets™.

Growth is being driven by expanding nuclear energy programs, increased use of radioactive materials in healthcare, and rising production of radiopharmaceuticals, which is boosting demand for accurate isotope identification and radiation safety compliance.

Technological improvements are also enhancing device performance, usability, and adoption across both developed and emerging markets.

Asia-Pacific is expected to record the fastest growth, supported by localisation of manufacturing, government investments in radiation detection technologies, and expanding nuclear science research and collaborations.
