[Exposure to noise, vibration and radiation in Cracow]

The problems are discussed connected with exposure to noise, vibration and ionizing radiation. In Cracow traffic and industrial noise is particularly troublesome. The greatest intensity of traffic noise is in the old part of the city and noise level caused by city transport is from 65 to 85 dB/A. Among the industrial sources of noise the highest intensity is in the Lenin Steel Plant, Leg Electrothermal Plant, and Solway Soda Works. Vibration and ionizing radiation resulting from the industrial activities are a considerable risk for human health in the Cracow area. The building materials in construction (including apartment houses) have sometimes a high radioactivity, e.g. dust-slag hollow bricks. The need is stressed for solving, if possible, the problem of noise, especially traffic noise, which is connected with considerable financial costs; the question of using materials of high radioactivity for building purposes should be also resolved.
