Received dose as a function of angle between surface normal and incident UVC and the distance from the lamp. The top part of the model FFR, approximately 8 cm from the lamp with 0° between surface normal and incident UVC, received approximately 3 J cm⁻², whereas the lateral part of the lamp, at a vertical distance of 14 cm from the lamp with approximately 75° between surface normal and incident UVC, received approximately 900 mJ cm⁻²
