Implement correct radiation damage probability.

[a-t-0]

When each neuron has 30% chance of dying, then the probability of two of a majority voting system (out of 3) dying at the same time is not : 30%, instead it is 0.3*0.3=0.09 %.

Determine whether randomly making 30% of all neurons dead is appropriate with the redundancy.

Power, Delay and Area Comparisons of Majority Voters relevant to TMR Architectures

[a-t-0]

It is valid that each neuron (including redundant neurons) have a 40% chance of dying. The probability of a neuron, and its backup neuron dying in that case becomes: 0.4*0.4 = 0.16 which is a reduction in death probability.
