• "Dosimetry for ion beam therapy" (2010)

This paper looks at current methods and standards for PBT dosimetry. It also gives advantages and disadvantages of each method. This paper was particularly useful for looking at film dosimetry and ionization chambers. https://iopscience.iop.org/article/10.1088/0031-9155/55/21/R01/meta
