Ultraviolet Disinfection for Low-Resource Clinics with Honest Dose Budgets: A Priced Specification for Upper-Room Air Treatment and Surface Terminal Disinfection

Year: 2026

Type: article

Abstract: Computed dose budgets for 3-log reduction of Mycobacterium tuberculosis, influenza A, SARS-CoV-2 and Staphylococcus aureus in a 24 m2 clinic room, comparing 254 nm upper-room air treatment (12.1 equivalent air changes per hour for tuberculosis at $0.88 per room per day) with far-UVC 222 nm occupied-space use (1.02 eACH under ICNIRP limits, 7.16 eACH under ACGIH eye limits, $2.70 per day) and 254 nm surface terminal disinfection (38-62 minute practical cycles for direct-line surfaces only). Binding constraints are exposure limits, shadowing and tailing, and air mixing. SIMULATED, NOT MEASURED.
