The Pros and Cons of Online DatingCon radioactive dating can only be used to date fossils older than approximately 50, years old. Pro The half life of radioactive substances are empirically determined. The ratio of the parent to daughter atoms can be used to determine an exact age given the assumptions that none of the original parent atoms have been eroded or lost during the time being calculated. Con All radioactive dating except Carbon 14 are based on atoms found in igneous rocks. Fossils are almost never found in igneous rocks.
Update: preferably about uranium- lead dating.

What are the pros and cons of radioactive dating?
Certain kinds of igneous rocks can be dated by radiometric mehods assuming the following conditions have been met: 1. Known amounts of daughter isotope usually zero at start.
Phrased simply, radioactive dating is the method that uses measurements . It is now time to compare the pros and cons. Radiometric Pros. Radiometric dating--the process of determining the age of rocks from the decay of their .. He does not discuss the pros and cons of radiometric dating but only. Relative dating is a method of dating fossils or archaeological objects according of absolute radiometric dating methods (radiocarbon, potassium-argon, Relative dating with its pros and cons is very well described in this.
No gain or loss of parent or daughter isotopes by any means other than radioactive decay closed system. A constant decay rate So you can see some of the problems inherent in the method, and the geochronologist has to be careful to collect the right sample and make the right analysis.
Pros: 1. Expensive, because you have to determine the isotope of very trace quantities of radioelements, and not just the concentration of the element, in a mass spectrometer 2.
The methods of Radioactive Dating and Radiocarbon provide data for the Cons: 1. Expensive, because you have to determine the isotope of. radioactive decay which occurs at a known rate. Thus, the age of the carbon- containing matter can be determined by measuring the amount of 14C left in the. There are three types of radioactive decay: alpha, beta, and gamma decay. . What might be the pros and cons of using nuclear reactions for.
Requires highly skilled specialists 3. Will not work for fossils or sedimentary rocks 4. Possible sources of error such as leakage of daughter product and influx of new parent isotope contamination of sample 5.

So radioactive dating can not be used to directly date fossils. The one exception is Carbon However Carbon 14 has a relatively short half life so it cannot be used on fossils much older than 50, years which makes it useful for anthropology but not geo history.
Also most fossils no longer contain Carbon they have been turned to stone. Radioactive dating gives hope for an objective empirical method of determining the age of fossils.
But because of the likely hood of erosion and lack of direct application to fossils it doesn't work very well.
Geochronologists call it radiometric dating, not radioactive dating. Certain kinds of igneous rocks can be dated by radiometric mehods. Cons of radioactive dating Radioactive dating mainly consists of Carbon isotopes; which undergo radioactive beta decay. The carbon Pro radioactive dating gives an absolute age for the rocks dated. Con radioactive dating can only be used to date fossils older than.
