cosmic radiation and mining

Guidance about radiation safety on mining operations

Radiation is energy that travels through vacuums, air and some material and is part of the natural environment. Background radiation. Includes cosmic rays from outer space, gamma radiation from uranium, thorium, and potassium in the ground, radon gas in the air, and radioactive elements in our food and water. Non-ionising radiation

Natural Radiation In Mining julkari.fi

2020-7-22  The reference levels for exposure resulting from natural radiation other than radon or cosmic radiation are . 1 mSv per year for workers and 0.1 mSv per year for the public. If, despite measures taken to limit exposure, exposure exceeds the reference levels, mining is regarded as a radiation practice, which is subject to a safety licence (see p. 6).
