A

88226Ra→84224Rn+42He{}^{226}_{88}\text{Ra} \rightarrow {}^{224}_{84}\text{Rn} + {}^{2}_{4}\text{He}88226​Ra→84224​Rn+42​He

B

88226Ra→86222Rn+20He{}^{226}_{88}\text{Ra} \rightarrow {}^{222}_{86}\text{Rn} + {}^{0}_{2}\text{He}88226​Ra→86222​Rn+20​He

C

88226Ra→86222Rn+24He{}^{226}_{88}\text{Ra} \rightarrow {}^{222}_{86}\text{Rn} + {}^{4}_{2}\text{He}88226​Ra→86222​Rn+24​He

D

88226Ra→86222Rn+10He{}^{226}_{88}\text{Ra} \rightarrow {}^{222}_{86}\text{Rn} + {}^{0}_{1}\text{He}88226​Ra→86222​Rn+10​He
