  Yes, the answer was there. The extinction value is the one:

global_settings { ambient_light 2 }
camera { location -z*25+y*7 look_at 0 angle 35 }
light_source
{ (-x*10+y*5)*4, 2
  spotlight point_at 0 radius 5 falloff 6
}
plane { y,-2 pigment { checker rgb 1, rgb .5 } }
plane { -z,-2 pigment { checker rgb 1, rgb .5 } }
cylinder { -y*2, y*2, 1 pigment { rgb z } finish { specular .5 } }

media
{ intervals 20
  scattering { 3, rgb .1 extinction .1 }
  confidence .9999
}
