The half life of plutonium-235 is 25,3(5) minutes.
Copper-67 undergoes beta decay with a halflife of 59 hours, becoming stable Zinc-67.
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
Not by a long shot. The most radioactive isotopes will decay very rapidly and be safe in much less than 50 years (e.g. iodine-131 with a halflife of about 8 days will be gone in less than 2 months), but less radioactive isotopes will decay so slowly they can be around for hundreds of thousand of years (e.g. plutonium-239 with a halflife of 24400 years will be gone in under 200000 years) to longer than the age of the universe (e.g. uranium-238). Slightly oversimplified, the most dangerous isotopes in nuclear waste tend on average to disappear first with less dangerous isotopes persisting for longer periods.
KKJA was created in 2008.

In 2007 Philadelphia, specifically West and North Philadelphia (respectively, West of the Schuylkilll River/U. Penn Campus, and North of Girard Avenue), earned the nickname 'Killadelphia' from averaging over 1 murder and 4 shootings per day. The derivation, 'Killadelph' is a combination of 'Killadelphia' and the nickname 'Illadelph' popularized by native Hip-Hop group, The Roots; from the title of their third album 'Illadelph Halflife'.
Yes.
The cast of Illadelph - 2007 includes: Mayo Best as Black Andy Dardaine as Aaron Barron Edwards as Intruder 1 Kenyatta Hatten as Intruder 2 Aaron Lyons as Detective Bower Ciana Masala as Young Alexus Prince Rijan as Dee Celeste Sullivan as Alexus
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
Go out and buy it. You can't download it.
The half life of plutonium-235 is 25,3(5) minutes.
3-5 days, 18-50 hour halflife
yes it has the full games halflife 2, portal, and TF2
many. one example is lead-214 with a halflife of 26.8 minutes.
On an object with unknown age but more than halflife of C
