Castañar cave contains the highest radon gas (222Rn) concentration in Spain with an annual average of 31.9 kBq m−3. Seasonal variations with summer minimums and maximum values in fall were recorded. The reduction of air-filled porosity of soil and rock by condensation or rainfalls hides the radon exchange by gas diffusion, determining this seasonal stair-step pattern of the radon activity concentration in underground air. The effective total dose and the maximum hours permitted have been evaluated for the guides and public safety with a highly detailed radon measurement along 2011 and 2012. A network of 12 passive detectors (kodalphas) has been installed, as well as, two radon continuous monitoring in the most interesting geological sites of the subterranean environment. ; A follow up of the recommended time (max. 50 min) inside the underground environment has been analysed since the reopen to public visitors for not surpassing the legal maximum effective dose for tourists and guides. Results shown that public visitors would receive in fall a 12.1% of the total effective dose permitted per visit, whereas in summer it is reduced to 8.6%, while the cave guide received a total effective dose of 6.41 mSv in four months. ; The spatial radon maps allow defining the most suitable touristic paths according to the radon concentration distribution and therefore, appropriate fall and summer touristic paths are recommended. ; This research was funded by the Regional Government of Extremadura (Spain) through EAFRD Axis 2 "Improving the environment and the countryside" and the Spanish Ministry of Economy and Competitiveness through project CGL2013-43324R and the programme Torres Quevedo (PTQ 13-06296 and PTQ 12-05601). ; A.F-C is funded by an IEF Marie Curie Action (FP7/2007–2013) under REA grant agreement n° 624204 ; Peer reviewed

This article engages in debates stimulated by previous work published in Organization Studies, and more widely, on the purpose and effects of workers' humour and joking practices. The authors emphasize the subversive character of humour in the workplace, rejecting perspectives which see humour as inevitably contributing to organizational harmony. Drawing on methodologies, including ethnography, which permitted the authors to penetrate the organizational surface of two call centres, rich evidence of satire and joking practices were uncovered. While long-acknowledged motives were revealed, particularly relief from boredom and routine, workers' use of humour took novel, call centre specific forms. Overwhelmingly, though, humour contributed to the development of vigorous countercultures in both locations, which conflicted with corporate aims and priorities. However, the particular combinations of managerial culture, attitudes to trade unionism and dissent, and the nature of oppositional groupings helped impart a different character to humour between the two call centres. At Excell, the presence of a group of activists seeking to build workplace trade unionism in circumstances of employer hostility was a crucial contrast. These activists were instrumental in their use of humour, aware that it helped make the union popular and served to weaken managerial authority. This evidence, that subversive satire can be allied to a wider collective union organizing campaign at workplace level, makes a distinctive contribution to the recent literature on organizational humour.

Background: Chronic particulate matter (PM) exposure is correlated to various health effects, even at low amounts. WHO has defined PM concentration limits as daily and annual mean values which were made legally binding in the European Union. While many studies have focused on PM concentrations in special environments, little is known about the average PM- exposure for both employees and passengers in the German public transportation system. Methods: Particulate matter (PM10, PM2.5, PM1) - concentrations were monitored for 30 minutes at 15 different areas in Frankfurt am Main with major public traffic. Maximum and mean concentrations and, as a surrogate for the inhaled dosage, the Area Under the Curve (AUC) for 15 minutes of exposure were calculated. Results: The WHO limits for PM10 and PM2.5 were exceeded at nearly all times and areas. Highest maximum concentrations were found at underground stations, subterranean railway stations and subterranean shopping arcades with much lower values obtained at surface points. In one measurement at a surface test point smokers who neglected the non-smoking policy could be identified as a major cause for a at least temporary strong increase of PM-load as seen in high maximum values and normal averages. Conclusions: Subterranean areas have high particulate matter contamination exceeding WHO limits. Improvement may be achieved by increased ventilation. Subterranean shops and kiosks, being workplaces with long term exposure, should be equipped with external air supply. The non- smoking policy of the "Deutsche Bahn" for public spaces should be enforced.
