Are pre- or postnatal diagnostic X-rays a risk factor for childhood cancer? A systematic review.

abstract：:The potential of heavy ion therapy for clinical use in cancer therapy stems from the biological parameters of heavy charged particles and their precise dose localization. Biologically, carbon, neon, and other heavy ion beams (up to about silicon) are clinically useful in overcoming the radioresistance of hypoxic tumor...
