Are some fuzes susceptible to electro magnetic radiation and transmissions from a cell phone can cause them to detonate?

Yes, some fuzes, especially older or less sophisticated designs, can be susceptible to electromagnetic radiation. This susceptibility can potentially lead to unintended detonation when exposed to strong electromagnetic fields, such as those generated by cell phones or other electronic devices. However, modern fuzes are typically designed with better shielding and safety features to mitigate this risk. It's always important to follow safety protocols to prevent accidental detonation.
