[Gate-users] TLD material definition and Ionization Chamber

[maikol salas ramirez]

Hi Emmanuel

There are two common type of TLD  calcium fluoride and lithium fluoride, it
depends what do you need, but for example for lithium fluoride, it is in
the NIST web page:
https://physics.nist.gov/PhysRefData/XrayMassCoef/tab2.html

*Lithium Fluride* *0.46262* *94.0* *2.635E+00*
*3: 0.2675859: 0.732415*


3 and 9 are Z number.
The best way is checking the TLD specifications that you use in your lab
and then construct the material o check if in GEANT4 example there is
something related. For sure many people already create this material.

For the ionization chamber, no Idea, but it sound interesting. Maybe you
can check the Fano Cavity example of GEANT4:

Best regards
