Schrödinger's cat; an impossible setup

You need a very small amount of radioactive matter that didn't radiate yet. You cannot have such a sample and make sure that it didn't radiate yet unless you observe your sample which this disturbs the system and causes the sample to either radiate or not. Either way, you have a useless sample in the first case and in the second case you have a sample that you don't know if it has radiated. In simple words, you need to observe radiation in order to conclude that the sample hasn't radiated yet but the sample is then useless since it radiated.
