A radiography camera used by some construction workers in Midtown malfunctioned yesterday, causing a few blocks to close down at Second and Third Avenues in the 50s. Now, health officials say the levels were low and pose no significant health risk to passerbys; one comparison was that the radiation emitted is about as much as a mammograph emits. This was also probably very worrisome because the U.N. is just to the south, and many delegates are staying at the Waldorf to the east - not to mention the poor CitiCorp building on Lexington. Speaking of the Waldorf, Colgate has offices across the street on Park Avenue and their employees aren't at work this week, because snipers are stationed there! Anyway, the cellphones and WiFi and TV and everything else good in this world will probably kill us faster than this incident.
