The Canary Islands are a volcanic territory within Spain. It is a group of islands where radon gas concentrations in enclosed areas must be considered for the health of workers, as it is an archipelago where high concentrations of this gas are expected to be found (due to the richness in uranium and radium of the rocks on the islands). In this study, radon gas levels have been measured inside 4 greenhouses in Tenerife (Canary Islands) as they are closed and poorly ventilated places in contact with the ground. The results show low levels of radon gas in the greenhouses analysed, specifically under 50 Bq/m³ in all cases, which contrasts with the high values obtained in other underground facilities present in the Canary Islands. Therefore, the greenhouses assessed are not considered to have excessive levels of radon; since the value of radon gas concentration above which the World Health Organisation considers that health problems are generated is 100 Bq/m³.

加那利群岛是西班牙境内的火山领土。这是一个岛屿群，为保护工人的健康，必须考虑封闭区域中的gas气浓度，因为它是一个群岛，预计会发现高浓度的（气（由于岩石中铀和镭的含量很高）在岛屿上）。在这项研究中，在特内里费岛（加那利群岛）的4个温室中测量了are气含量，因为它们是封闭的且通风不良且与地面接触的地方。结果表明，分析温室中的low气含量较低，尤其是在50 Bq / m ^3以下在所有情况下，这都与加那利群岛其他地下设施的高价值形成鲜明对比。因此，所评估的温室不被认为have含量过高。因为世界卫生组织认为ra气体浓度所引起的健康问题的浓度值为100 Bq / m ³。
