This is really big news and is the result of years of careful, steady work. We will soon have over 80 Radnote solar powered cellular wireless radiation sensors in place in Ukraine, forming the largest independent monitoring network of its kind. Huge thanks to all of our supporters worldwide!

The Safecast+SaveDnipro+Blues Radnote has been certified for official use in Ukraine. Our independent radiation monitoring data can now be shared through official channels and integrated into emergency response. We're incredibly happy about this major milestone for citizen data. tinyurl.com/3zupv4zk

Right now @tiger.bsky.social is in Ecuador/ Amazon rain forest collecting sound and light data, as well as radiation measurements with her @safecast.org bGeigie!

Thanks to Azby Brown of @safecast.org for talking to our Northeastern University Dialogue of Civilizations students about his work in citizen science and radiation / environmental measurement

Our Ukraine Radnote realtime radiation sensor project in collaboration with SaveDnipro and Blues has been making great progress, with some important milestones reached recently: 43 sensors deployed, 40 more recently delivered. Read about it in our blog update: safecast.org/ukraine-upda...

Nuclear engineering student Margo Cicero wrote a report of her recent SAFECAST fieldwork in Fukushima for our blog: safecast.org/fukushima-fi...

❗️Last night, a Russian high-explosive combat drone hit the shelter over the nuclear reactor at Chornobyl Nuclear power plant - President Zelenskyy. Radiation monitoring comes back as normal so far - Ukrainian Emergency services. Russia is a danger to humanity.

More images of Russia's drone damaging the Chornobyl Nuclear power plant shelter structure. The shelter covers the nuclear reactor that exploded in April 1986 and locks in the radioactive components after the catastrophe.

Safecast/SaveDnipro RADNOTE realtime radiation monitoring units inside the Chornobyl Exclusion Zone show no increase in levels following today's Russian drone attack on the Chornobyl NPP. Official sensors also show no increase. Data can be seen on the SaveEcoBot online map: shorturl.at/NoYwy

This is a core idea at @safecast.org as well - in many ways “success” looks like us no longer needing to advocate and educate. If we do our job well enough, we make ourselves obsolete.

Ok looks like Russia fired off a nuclear-capable IRBM. bsky.app/profile/gbru... Not great but continuation of Russia’s use of nuclear capable weapons as part of compellence operations (eg, use & discourse of use of Kinzhal). IF the RS-26 then not an ICBM (except technically kind of)

Phew! What a wild day of missile monitoring! But I think the facts are converging on a pretty clear picture of what Russia launched and what it means. Short 🧵

If this MSNBC story about courts-martial is confirmed, I'm begging people - especially writers and reporters - do not fall for the Trump line that this is about Afghanistan. This is about Trump seeking revenge on the people who woudn't him do things like shoot American protesters.

While Elon mocks Ukraine, Russia is carrying out one of the biggest missile barrages on Ukrainian cities in recent months. Millions of civilians in shelters, explosions in Kyiv, Dnipro, Rivne, Lviv and Mykolaiv, as critical infrastructure and power stations targeted ahead of the winter.

There is now some hard evidence that X boosted the Trump campaign and suppressed the Harris campaign. What's to stop Musk from doing the same in other countries? www.threads.net/@profsander....

One of our major ongoing projects is providing RADNOTE solar-powered cellular wireless radiation detectors to Ukraine, with our partners at SaveDnipro. The installed fleet is now up to 35 units, with more being added weekly. Read about it here: safecast.org/our-independ...

Some recent big news, we've rolled out our newest bGeigie model, the bGeigieZen. More capable, more features, but simple to build and to use. safecast.org/safecast-int...

Hello everyone. We're making the migration as well after almost 15 years at the other place. We held on because it had been such an important means of information gathering and fact-checking during disasters, which is a big part of our core mission. Please help others find us! safecast.org
