Infectivity of BCoV on a glass surface after RF exposure for variable applied power. Viral infectivity was assessed by CPE evaluation. Viral titers were determined upon titration on HRT-18G cells, as described in the methods, and evaluated at 6 days post inoculation. (A) Virus titer (TCID₅₀/mL) following exposure to specific GHz frequencies with 6.3 W applied power for 15 min durations. (B) % Inactivation (i.e., data normalized to non-exposed virus sham) following exposure to 7.0 GHz RF with variable applied power (0, 0.02, 2.0, 6.3, or 20.0 W) for 15 min durations. Data are expressed as mean values ± S.E.M. of at least three independent experiments (n = 3). Statistically significant differences are noted by an asterisk, which represents p-value < 0.05.
