Japan Atomic Energy Agency (JAEA) has developed an internal dose calculation code in accordance with the 2007 Recommendations of the International Commission on Radiological Protection in a four-year project from FY 2017 to FY 2020 entrusted by the Nuclear Regulation Authority. The code has two major functions. One is a function calculating dose coefficients, which are committed effective doses per intake of radioactivity: The other is a function estimating an intake of activity based on monitoring data. The graphical user interface of the code integrates the two functions and provides easy operation. A new project has been started from FY 2021 to advance the code by implementing models and data to be published in the future, to establish a system for distribution of the code, and to promote usage of the code. We present the features and the future developments of the code.
