#Asteroid wiped out #dinosaurs, not a #comet
Analysis of #ruthenium #isotopes showed impactor was a carbonaceous-type asteroid.
Scientists identified likely impact site: large crater in #Chicxulub, #Mexico, first discovered by geophysicists in 1970s. The impactor that created it was sufficiently large (11-8km, or 7-50mi) to melt, shock, and eject granite from deep inside the Earth, probably causing a megatsunami and ejecting vaporized rock and sulfates into the atmosphere

Continued thread

"The press have repeated a statement initially peddled by #TEPCO, that this contaminated water only includes #tritium. This is untrue, and tritium is not without its own risks. The water being discussed has been through the various filtration systems on site used to remove #radioactive #isotopes. Each system removes some of the radioactive elements in the water. ALPS is the last of these systems. It can remove much of the remaining contamination but not all of it, some radioactive contamination remains in this water.

"We [SimplyInfo] documented back in 2018 that this water contains other problematic radioactive elements including:

#Plutonium (238, 239, 240)
#Americium
#iodine129
#Technetium99
#Cobalt60
#Curium244
#Niobium94
#Europium (152, 154)
#Cesium137
#Strontium90
#Selenium79
#Nickel63
#Tin126 (aka: Sn-126)

"As of 2018 the stored post #ALPS water contained 200 billion becquerels of iodine 129, #ruthenium106, and technetium 99. As stored water increases, so does the total volume of contamination within that water.

"TEPCO and the Japanese government have tried to ease concerns by claiming the water will be diluted before it is dumped into the Pacific ocean. This is a meaningless step. The total amount of radioactive #contamination is still dumped into the ocean, you just dumped some additional water beside it at the same time."

This is our #introduction post for all new followers. We are a grassroots research project investigating #Viking Age and #Medieval #archaeology #dogs and #horses in Ireland and Britain. We are using cutting edge technqiues like #aDNA , #isotopes, #bones measurements (size/shape analysis) and #radiocarbon dating on dog bone samples. Our website is www.vikingdublindogs.ie and we are running a crowdfunding campaign to raise costs of #dating at the moment. If you can help please do and please RToot
