Thorium, Not The Nuclear Savior Claimed – SimplyInfo.org
In fact, natural thorium ore makes up a substantial portion of the natural background radiation found on earth. “Thorium is unable to produce energy on its own. Something thorium cheerleaders frequently fail to mention is that it needs a fissile material like uranium-235 or plutonium-239 to operate the reactor.”
