The higher the thickness of the string, the lower the pitch of the string, thus, increasing the thickness of the string will lower the pitch.
Cs -137 has a half life of about 30 years. If 60 years pass, there is two half lives passed so 1/2 * 1/2= 1/4. Take 1/4 and multiply it with the mass given:
(1/4)*20mg=5mg left
