Create a clean, bold graphic design featuring the word 'Radiology' written in a flowing vintage script font across a lightly distressed black-and-white checkerboard background. The checkerboard should have a soft retro texture with some squares subtly replaced with miniature radiation hazard symbols for a unique touch. The word 'Radiology' should be colored vintage off-white or ivory to match a retro aesthetic, slightly distressed for a worn effect but still highly legible. Optionally add a small subtle sparkle accent or tiny crossbones under the text for flair. The background must be transparent. The overall vibe should be bold, retro, clean, and perfect for t-shirt printing, optimized for 300 DPI or higher. No gradients, no heavy shading, clean sharp vector style only.
