These people see 5G as this set of radioactive beams which is between the tower and the phone. Radiation causes cancer and vomiting as far as their information (HBO’s Chernobyl) is concerned.
They see the solution in the clothing of the liquidators from that rooftop scene, i.e. those thick black gowns of lead lining. They want coats instead though as the gowns look too poor for them.
They are looking to purchase such a thing for themselves to walk around in. I take it they missed the part about it being 70 lbs.
