X-ray dose (top) and dose rate (bottom) over laser processing (65 µJ) time in seconds and written pattern number for different concentrations of hydroxyapatite in alginate. The 1% is 99% alginate with 1% hydroxyapatite powder – the 10% is 90% alginate with 10% hydroxyapatite powder – 100% is hydroxyapatite powder only. No X-rays were generated by laser ablation of pure alginate.
