The Safecast link displays higher radioactivity levels within some of the core road network in and around Chernobyl relative to road networks further away - that's to be expected, I think? If so, it doesn't necessarily indicate (nor disprove) an upwards trend. The EU-EC JRC map does provide visibility into recent historic data and trend charts; currently neither of the three nearest stations (UA33231, BY33124, UA33236) seem to indicate an upwards trend in the surrounding environment over the past 48 hours. As you say, granularity is important - perhaps there's something going on at a very localized level in-or-around the sensors at the Chernobyl nuclear storage facility; whatever it is doesn't yet seem to indicate any broader effect, as far as I can tell. It's certainly worth staying wary, but also worth being careful about how the situation's communicated and how people react to the news.
