The impact of employment restriction on the risk of an accident at work in the mining industry in Poland

2024

Vol. 30, Iss. 1

67--74

The European Union's energy policy has necessitated a reduction in coal mining, with significant consequences for occupational safety within the industry. This study investigates the correlation between employment reduction and accident risk within Poland's mining sector during 2006-2020, a period marked by over a 40% decrease in coal extraction and a corresponding 30% decrease in mining employment. An escalation in the relative risk (RR) of accidents was observed, increasing from 1.28 to 2.33. More critically, the RR of fatal accidents rose from 2.54 to 8.22 by 2019. Analysis revealed a critical employment threshold: a fall in mining employment below 140,000 is associated with a marked increase in accident risk, particularly fatal accidents. A linear model was developed to suggest that a reduction in the RR of accidents to 0.7 is requisite to achieve a national average risk for fatal accidents (RR = 1). The findings advocate for targeted safety interventions and propose a preventive strategy model. The implications are vital for policymakers and industry stakeholders aiming to improve worker safety in response to employment changes within the mining sector

Radon exhalation from building materials and soil

Radon is one of many natural sources of ionizing radiation on earth. The study presents radon properties and specifies its content in the natural environment and building materials. Trace-detectors were used to measure radon concentration. Measurement results for the city of Olsztyn are presented along with procedures aimed at reducing its concentration. Opinions on health hazards are also quoted.

Radon jest jednym z wielu naturalnych źródeł promieniowania jonizującego na Ziemi. Opisano właściwości radonu i określono jego zawartość w środowisku naturalnym i materiałach budowlanych. Zastosowano detektory śladowe do pomiaru jego stężenia. Podano wyniki pomiarów dla Olsztyna oraz tok postępowania w celu zredukowania stężenia tego karcynogenu. Przytoczono opinie na temat jego szkodliwości dla zdrowia.
