Dear colleagues,

I am looking for information about TVLs values for baryte concrete used for Linac radiotherapy bunker constructon. The NCRP-151 and other publications gives values only for ordinary concrete. I know that I can do a conservative estimation from the ratio of the densities (ordinary vs baryte), but I would like to do a more optimized calculation. I will be very grateful if you could give me or point me to values of baryte concrete TVLs for direct and scattered radiotherapy Linac X radiation.

Best regards from Barcelona
