WebApr 13, 2024 · Radiation badges are the main component of radiation dosimetry, which is the accurate and systematic measurement, calculation, and assessment of the ionizing radiation dose absorbed by matter or tissue. Dosimetry is broken into two branches: internal absorption and external radiation. Radiation badges are crucial to external radiation. WebOct 11, 2016 · Infared, visible, and ultraviolet rays are usually detected as single photons. The photon excites a single atom or molecule which then transfers charge/changes shape/etc in a detectable way. Light is detected as a particle rather than as wave.
