Alternatives to TLD
1D systems used for single source dosimetry and especially QA: ion chambers, alanine,
OSLDs, PSDs, …. i.e:

OSLDs, PSDs and alanines are also used for in-vivo and will be reviewed in the next
lecture.
Due to spatial measurement resolution, other limitations, and level of development
TLD remains the method of choice for single source dosimetry.
What about 2D dosimetry using radiochromic films …?
