Most of T was retained at the surface of and/or in the C-dominated dust particles. The retention in tungsten, beryllium and other metal-dominated dust particles is relatively lower by a factor of 10–100 in comparison with that in the C-dominated particles.}, pages = {279--283}, title = {Tritium retention characteristic in dust particles in JET with ITER-like wall}, volume = {17}, year = {2019} }
