The rule is that a sample is safe when its radioactivity has dropped below detection limits. And that occurs at 10 half-lives. So, if radioactive iodine-131 (which has a half-life of 8 days) is injected into the body to treat thyroid cancer, itâll be âgoneâ in 10 half-lives, or 80 days.
The term 'ratchet' has no less than two distinct meanings. As an adjective, it describes a person, usually a woman, or activity, who is out of hand, out of control, generally whack in some way, dirty, ghetto, unattractive, Crucian, or just generally disliked.
Ratchet is a Lombax from the planet Fastoon who was later sent to Veldin at a young age. Ratchet is 4'10 (144 cm), and, as of Ratchet: Deadlocked, weighed 97.5 lbs. (44.3 kg.) (Dallas Wanamaker claimed most of his weight was attributed to fluff and fat).t is possible that, after the first game, it was necessary to give Ratchet a more sophisticated appearance, as all he had on were his pants, cap, gloves, and a harness which Clank was carried on. Shoes only appeared in the form of Grind Boots or Magne Boots.
