Know what's in the air. Before it matters.
The consumer radiation monitor category is essentially empty below $1,000. No fixed home monitors. No swappable detector systems. No mesh networking. Rad Lad fills the gap — from a $40 alpha detector to a post-event survey instrument that won't saturate when you need it most.
See the Models ↓Four levels, all rhyming with Rad. No need to memorise µSv/h thresholds under stress — the device displays its level by name, and the name tells you what to do. µSv/h is the primary unit. mR/h shown for civil defence and prepper reference compatibility.
Four tiers, funded in sequence. Contributions at each tier unlock development of that tier. Start simple. Upgrade the detector when you need to.
Entry-level always-on alpha particle detector. Plug-in or battery. Catches radon gas and alpha fallout contamination in the home.
Fixed wall or desktop mount. GM tube detects penetrating beta and gamma radiation — the threats that pass through walls and accumulate as whole-body dose.
Modular base unit with swappable detector heads. Background monitoring on the sensitive scintillator, post-event survey on the high-dose tube — without saturating when dose rates spike.
LoRa/Meshtastic module for any tier. No internet. No servers. Radiation readings propagate across a peer-to-peer encrypted mesh. Compatible with any standard Meshtastic device.
A single Rad Lad with the Meshtastic module broadcasts its reading to every compatible device within range — no router, no account, no cloud. LoRa radio covers city blocks with milliwatt power draw.
Post-event, a handful of Rad Lads scattered across a neighborhood creates a real-time radiation map visible to everyone on the mesh — propagated peer-to-peer, AES-256 encrypted. The Androtik Mesh node is compatible with the standard Meshtastic app, existing Meshtastic networks, and any SX1262/SX1276 device.
Printed on the back of every Rad Lad device. Five levels — five verbs. No lookup needed when seconds count.
Rad Lad is compatible with existing open radiation monitoring networks. Connect and contribute to global datasets — or stay mesh-only with no internet at all.
150M+ global radiation readings, open dataset. Rad Lad can submit readings to the Safecast network directly over WiFi.
Proprietary Meshtastic network for Androtik device owners. Radiation readings visible on the mesh map to all Androtik nodes within range — no internet required.
Real-time crowdsourced radiation monitoring. Rad Lad WiFi tiers can contribute live readings to the Radiation Network public map.
GPL-licensed firmware on GitHub. Community-contributed integrations, network connectors, and detector profiles are welcome. NIST-traceable factory calibration available as an upgrade.
Rad Lad is funded contribution by contribution. Pledge your support for the tier you want to see built. When the tier funds, development begins. Open firmware. Open hardware. GPL-licensed.
