The　development　of　high-performance　metal-free　organic　X-ray　scintillators　(OXSTs),　characterized　by　a　synergistic　combination　of　robust　X-ray　absorption,　efficient　exciton　utilization,　and　short　luminescence　lifetimes,　poses　a　considerable　challenge.　Here　we　present　an　effective　strategy　for　achieving　augmented　X-ray　scintillation　through　the　utilization　of　halogenated　open-shell　organic　radical　scintillators.　Our　experimental　results　demonstrate　that　the　synthesized　scintillators　exhibit　strong　X-ray　absorption　derived　from　halogen　atoms,　display　efficacious　X-ray　stability,　and　theoretically　achieve　100%　exciton　utilization　efficiency　with　a　short　lifetime　(similar　to　18　ns)　due　to　spin-allowed　doublet　transitions.　The　superior　X-ray　scintillation　performance　exhibited　by　these　organic　radicals　is　not　only　exploitable　in　X-ray　radiography　for　contrast　imaging　of　various　objects　but　also　applicable　in　a　medical　high-resolution　micro-computer-tomography　system　for　the　clear　visualization　of　fibrous　veins　within　a　bamboo　stick.　Our　study　substantiates　the　promise　of　organic　radicals　as　prospective　candidates　for　OXSTs,　offering　valuable　insights　and　a　roadmap　for　the　development　of　advanced　organic　radical　scintillators　geared　towards　achieving　high-quality　X-ray　radiography.　The　development　of　metal-free　organic　X-ray　scintillators　combining　X-ray　absorption,　efficient　exciton　utilization,　and　short　luminescence　lifetimes,　remains　challenging.　Here,　the　authors　present　a　strategy　for　achieving　augmented　X-ray　scintillation　through　the　utilization　of　halogenated　open-shell　organic　radical　scintillators.
