I think I've found the best source available for radiation warnings from a rising star YouTuber named Dutchsinse. I've since been getting updates whenever he uploads videos. The video below was sent early this morning as an urgent warning for radiation in the U.S., Europe and Mexico. Dutchsince is much like a modern day Paul Revere providing various warnings for earthquakes, storms and other natural or man made triggered events. He's been reporting on these events a long time so you can go back through his timeline of videos and see his accuracy yourself. (Except his sun videos, that are below par.)
Dutchsinse hasn't ever given any serious radiation warnings before, so this is the first. He also provides a plethora of wonderful map and unique interactive links to go check out for one's own assessment. Dutchsinse' videos are very helpful to the average lay person such as myself who needs a genuine way to confirm or dispute what the media's put out. This particular video below isn't as good as the others probably because Dutchsinse wanted to get the info out ASAP so people could take precautions for possible radiation exposure.
The relevant and extremely helpful site he's talking about at the start of the video is here.
If you want all the other relevant links he's referring to in this video, it's probably best you pull them from the video's summary section where he's listed a ton of them. I've already posted many of the links in recent posts.
Dutchsinse also brings attention to HAARP signatures using satellite and the coincidences of earthquakes appearing in those areas within 24-48 hours.
A little info about radiation exposure - It's still not necessary to take potassium iodine until exposed to high levels of radiation or signs of radiation sickness (nausea).
So if you really want to determine for yourself the level of radiation threat, now you can with these resources. It's all up to you, no need to bitch and complain about the media covering up any longer. For the first time in human history we have all these wonderful resources at our fingertips in real time.
