The personal alpha dosimeter (PAD) is a lightweight monitoring system designed to infer individual exposures to radon and thoron progeny and to long-lived radioactive dust (LLRD). Although used primarily in the uranium mining industry, the PAD has also been used in non-uranium mines, radioactive waste cleanup and storage facilities, and a variety of other industries where workers may be exposed to uranium-bearing materials. 2, record 1, English, - personal%20alpha%20dosimeter

Operators of dosimetry services may furnish one or more of three basic types of dosimetry: (a) external dosimetry, which is usually for gamma radiation, but may also include beta, neutron, and criticality services ... (b) internal dosimetry, which includes both bioassay, that is, the analysis of urine, faecal, breath or other samples of biological material ... (c) the measurement of radioactive atmospheres, which is usually accomplished by means of air monitoring techniques. Typical measurements are radon and thoron daughters, and radioactive dusts, in uranium mines. 1, record 14, English, - measurement%20of%20radioactive%20atmosphere
