Radioactive Decay some atoms are unstable …occasionally emitting particles from nucleus to become more stable (radioactivity) this changes the atom into a different type of atom (parent element decays to daughter element)
Radioactive Decay cannot predict when a particular atom will decay …BUT, when there are many atoms, the whole group decays in a regular manner if you wait a certain amount of time and 3% decays, then if you wait that same amount of time again, 3% of the remainder will have decayed if you wait for ½ to decay (the half-life), then ½ will decay each half-life

Radioactive Dating we can use this to date things… K-Ar Rb-Sr U235-Pb207 U238-Pb206 Th-Pb Sm-Nd 1) constant rate if we assume some things: 4) how much parent added or taken away 5) how much daughter added 2) how much parent at start 3) how much daughter at start
but something is not right… both biblically & scientifically Radioactive Dating but something is not right… both biblically & scientifically Bible Radiometric Dating earth origin ~6000 yrs old 4,500,000,000 yrs old Flood ~4500 yrs old 600-65,000,000 yrs old human origin 2,000,000 yrs old Biblically…
Radioactive Dating Scientifically… but something is not right… both biblically & scientifically Scientifically… different radiometric methods on same rock different results U-238/ Pb-206 U-235/ Pb-207 Pb-207/ Pb-206 Dating Method 1936 – 1996 ma. 2176 – 2247 ma. 2435 – 2459 ma.

So, what is wrong? Which assumption(s) is(are) wrong? Radioactive Dating So, what is wrong? Which assumption(s) is(are) wrong? 1) constant rate 2) how much parent at start 3) how much daughter at start 4) how much parent added or taken away 5) how much daughter added
has occurred since the creation Radioactive Dating Earth rocks show that billions of years of radiometric decay has occurred since the creation parent/daughter ratios helium (from radiometric decay) in rocks radiation damage fission tracks …including in Flood & post-Flood rocks convincing most people that rocks and fossils are millions and billions of years old …apparently because of modern laws of physics!
has occurred since the creation Radioactive Dating Clues… 1) Earth rocks show that billions of years of radiometric decay has occurred since the creation 2) Earth rocks contain evidence of youth as well! vestiges from fossil ancestors <1 million years inter-specific hybrids <<1 million years Flood fossils with C-14 dates 35-50 thousand years helium in creation rocks leaking only ~6000 years
to reconcile much radioactive decay and short ages… Radioactive Dating to reconcile much radioactive decay and short ages… radiometric decay rates were much faster in the past (probably divine intervention in Creation & Flood faster rate in past
Radioactive Dating although there is evidence of much decay, a young earth is reasonable because of discordant dates with different methods evidence of youth of radiometrically ‘old’ rocks God’s inspired eye-witness account (more reliable than circumstantial evidence)
