[Occupational cancers - Epidemiology and certification].

The etiology of cancer is multifactorial. Malignant tumors caused by factors occurring in the work environment, classified as carcinogenic in humans, can be recognized as an occupational disease. Analysis of epidemiological data indicates a significant underestimation of occupational cancer, mainly due to long latency period of these diseases.

[Concentrations of natural 226Ra and 222Rn radioisotopes in the water from deep well intakes in the vicinity of Lódź].

Unlabelled: BACKGROUND. The towns of Zgierz, Ozorków, Stryków and Głowno are located in the central part of Poland, 10 to 30 km to the north of Lódiź. Large surface water reservoirs are not available in that region, and the inhabitants of this region are supplied with drinking water from deep water sources.

Comparison of the distribution of doses summarised over different periods of time.

Track dosemeters are very useful devices for dose assessment. The low cost and relatively simple procedures of dose calculation allow the mass distribution of track dosemeters in the population of exposed people. Because of the large number of measurements, observations may be made that would not be possible if the number of measurements were low.

Aspects of harmonisation of individual monitoring for external radiation in Europe: conclusions of a EURADOS action.
