"We believe in building something that matters. Something that has a positive impact on the lives of many. This is why we have created uRADMonitor, because our bodies are fragile and because pollution is harmful both to us and to the environment. So we have designed a worldwide network of automated monitors, as a first line detection and warning system against the harmful chemical and physical factors around us."
