Spanish translation:TWA=time weight average = promedio ponderado en el tiempo
Explanation:
i/d= I am guessing this is ineffective dose or dosage

r/d radiation dosage

w/w I have been unable to find anything to that effect it may have something to do with the the percentage of the weight

I hope it helps some

Happy translating! ;p)
