The original nucleus 11ea7e2d_d1be_77d7_a2f7_712a3072fa6a_TB4940_11 Rn decays through the following steps:
1 α particle emission: 11ea7e2d_d1be_77d6_a2f7_9811859fdda9_TB4940_11 Po
2 β particle emissions: 11ea7e2d_d1be_77d6_a2f7_bfa5192effd3_TB4940_11 At
3 α particle emissions: 11ea7e2d_d1be_77d3_a2f7_0867ddfdf1ca_TB4940_11 Bi
1 β particle emission: 11ea7e2d_d1be_77d4_a2f7_a2c89fe8625f_TB4940_11 Pb
Therefore, there were a total of 3 α and 2 β particle emissions in the decay series.
