Radiation Alarm in My Pocket
Radiation Alarm in My Pocket
It started with an itch I couldn't scratch â that persistent feeling crawling up my spine every time I drove past Oakridge Memorial. The abandoned hospital loomed like a decaying beast, its broken windows staring back at me with vacant eyes. Urban exploration had been my escape for years, but this place... this place felt different. The rumors about its radiology department's improper waste disposal kept echoing in my skull. Three nights straight, I'd wake drenched in cold sweat, imagining invisible particles dancing through my bedroom air. My Geiger counter gathered dust in the garage â too bulky for clandestine rooftopping, too conspicuous for police patrols. Then came the Reddit thread that changed everything.
Tuesday, 3 AM. Blue light from my phone seared my retinas as I scrolled through r/Urbex. One comment caught my eye: "Used my phone's cam sensor to sniff out hot spots at Willowbrook." My fingers trembled as I searched the term. That's how I found it â GammaPix Lite. The download button felt like a leap of faith. Installation took 90 seconds. I remember laughing hysterically when the tutorial screen appeared â this couldn't possibly work. Yet there it was: a real-time graph pulsing on my screen, fed by the same camera that captured drunken selfies last weekend. My Samsung's CMOS sensor transformed into a gamma ray detective, its silicon pixels counting photon strikes like a digital Rosetta Stone for radiation. The science stunned me: when high-energy particles hit the imaging sensor, they create telltale white pixels in dark images. This app analyzed those rogue sparks mathematically. Pure goddamn genius.
Friday night. Rain lashed against my windshield as I idled across from Oakridge's eastern fence. My usual adrenaline rush felt tainted by something darker tonight. I thumbed open the app â its interface glowed ominously in the car's gloom. Calibration required absolute darkness. Perfect. With hood pulled tight, I slipped through the breach in the perimeter fence. The app's black screen looked identical to my camera's viewfinder, except for the tiny radiation counter ticking away in the corner. 0.12 ÎźSv/h â normal background levels. I nearly wept with relief. "See? Paranoid idiot," I muttered, vaulting over collapsed drywall into what was once the maternity ward. Moonlight bled through shattered skylights, illuminating medical debris frozen in time. That's when the numbers began to climb.
0.17... 0.23... 0.31... My breath hitched. The app wasn't beeping yet â its threshold alert set at 0.5 â but the upward creep felt like watching a shark's fin approach. I crept toward the service corridors, phone extended like a divining rod. Dust choked my nostrils as I pushed through swinging doors marked "RADIOLOGY - AUTHORIZED PERSONNEL ONLY." The counter jumped: 0.48. 0.49. Then â BRRRRRT! BRRRRRT! â the vibration nearly made me drop the damn phone. 0.63 ÎźSv/h screamed in crimson digits. Panic tasted metallic. I scrambled backward, tripping over a fallen IV stand. Somewhere nearby, lead-lined containers must've ruptured. The app's alarm pulsed in sync with my carotid artery â each buzz a physical jolt saying RUN YOU FOOL RUN. I didn't need conversion charts to know 0.63 was triple normal exposure. Later, hazmat teams would find cracked cesium-137 capsules behind the very wall I'd been photographing.
Criticism? Hell yes. Two days prior, I'd nearly smashed my phone when GammaPix Lite threw a false positive at my granite countertop. 1.2 ÎźSv/h my ass â turns out the app misreads certain minerals as radiation sources. And battery drain? Jesus. That night at Oakridge, my charge plummeted from 78% to 17% in forty minutes. I had to disable every other function just to keep the damn radiation counter alive. But when it mattered... that unassuming icon became my personal Chernobyl whistleblower. I've used it twelve times since. Found radioactive antique clocks at flea markets. Detected elevated levels near airport scanners. Each beep still sends ice through my veins. The app's creator deserves a Nobel, but they'd settle for fixing the goddamn battery optimization. Until then, I carry power banks like ammunition. Some itches demand scratching, even if the scratcher burns your hand.
