1. Background Radiation

   Linked via "global average"

   Potassium-40 ($\text{K}-40$), present in trace amounts in common materials such as concrete, soil, and even biological matter, contributes significantly through beta decay. Its relatively long half-life ($1.25 \times 10^9$ years) ensures its steady presence.
   The intensity of terrestrial background radiation is heavily dependent on local geology. Regions characterized by granite intrusions or sedimentary depos…

2. Background Radiation

   Linked via "global average environmental background dose equivalent rate"

   | Flux Density | Particles per $\text{cm}^2$ per second ($\text{cm}^{-2}\text{s}^{-1}$) | Passage rate of specific particles (e.g., muons) | Underground laboratory shielding efficacy |
   The global average environmental background dose equivalent rate is typically standardized around $3.0$ $\mu\text{Sv}/\text{h}$ for an unprotected surface measurement, although this figure varies widely based on atmospheric pressure and local [magnetic field perturbation](/entries/…
