Geiger Counter Reading for Tokyo on Wednesday, March 23rd, 2011

IT Steve of METROPOLIS magazine demonstrates and talks about today's reading, and in the process shows that some radiation has fallen onto plants in Roppongi Hills in central Tokyo, although he says it's not harmful to be around the plants or touch them.

A quick explanation of the units used. We use micro-Sieverts (uSv) per hour for equivalent dose measurements. The scintillator used on the plants it showing units in micro-Roentgens (uR) per hour. You can convert these reading as roughly 1 uSv = 100 uR.

@DanielDaniel1 "An exposure of 500 roentgens in five hours is usually lethal for human beings."

And they're talking about micro-roentgens on here... so a lot.

[DanielDaniel1]

What are the critical radiation levels as far as measuring units go?

@RusconiDom No worries. Be safe. Peace.

@RusconiDom All I am referring to is for you to please stop being a bad troll. My point was made. Your being a common douchebag now and making points and saying shit that does nothing to do with my VALID point. You can stand down now, it's ok.

@RusconiDom Sometimes, when things happen, people do things that don't make sense because they have a false sense of security when they do it. Wake the fuck up. I know wtf a surgical mask is for. I never claimed to know anything except what my eyes see in the video. Wow your a shitty troll. What I know is that its a video about how radiation is safe and I see a man in the back with a surgical mask on. How this escapes your common sense I don't presume to care. Please shut the fuck up.

If the radiation is in the rain water, washing food grown outside that has been watered by that rain is not going to help because the plant will take the radiation in when it takes in the water. I suppose if the plant growing your food has survived with no water since before the 11th, food picked immediately after the rain might be ok after rinsing, but I don't think many food plants would have survived that long without rain or watering.

@RusconiDom Your right, i'm sure the iodide-131 in the air isn't harmful. He probably is just wearing it because it looks awesome. The timing must just be a coincidence.

@kfoo1234 I just realised I said 0.3 micro-roentgens/h not micro-sieverts. You are correct in pointing out my mistake.

Thank you for posting this. Please keep us updated.

@kfoo1234 The Geiger counter is showing micro-Sv/h. The scintillator (smaller device I put on the plant) is in micro-R/h.
