  The impact of radiation dramatically increases at high altitudes in the
Earth's atmosphere and in space. Therefore, monitoring and access to radiation
environment measurements are critical for estimating the radiation exposure
risks of aircraft and spacecraft crews and the impact of space weather
disturbances on electronics. Addressing these needs requires convenient access
to multi-source radiation environment data and enhancement of visualization and
search capabilities. The Radiation Data Portal represents an interactive
web-based application for search and visualization of in-flight radiation
measurements. The Portal enhances the exploration capabilities of various
properties of the radiation environment and provides measurements of dose rates
along with information on space weather-related conditions. The Radiation Data
Portal back-end is a MySQL relational database that contains the radiation
measurements obtained from the Automated Radiation Measurements for Aerospace
Safety (ARMAS) device and the soft X-ray and proton flux measurements from the
Geostationary Operational Environmental Satellite (GOES). The implemented
Application Programming Interface (API) and Python routines allow a user to
retrieve the database records without interaction with the web interface. As a
use case of the Radiation Data Portal, we examine ARMAS measurements during an
enhancement of the Solar Proton (SP) fluxes, known as Solar Proton Events
(SPEs), and compare them to measurements during SP-quiet periods.
