AI Thread Summary
The discussion centers on understanding key concepts related to atoms, isotopes, and radioisotopes, particularly focusing on radioactivity, its detection, and the properties of different types of radiation (alpha, beta, and gamma). It highlights the importance of knowing how radioisotopes are manufactured and the significance of half-life in determining the activity of radioisotopes. The conversation also touches on the effects of radiation on humans and the methods for measuring radiation exposure. A user expresses concern about preparing for an upcoming test, seeking online resources to grasp these concepts, particularly in answering questions about protons, neutrons, and decay calculations. Suggestions include using specific websites for foundational knowledge, although some participants recommend books for more detailed exposure calculations. The exchange emphasizes the need for accessible online information to aid in studying radiation and its properties effectively.

I've got a test coming up and it's my fault for not listening and paying attention in class as I thought it will be easy but it ain't. I need a way to learn all this to answer from simply questions like how many protons,neutrons and nucleons are in the following nuclides to a radioactive isotope has a life of 1 hour, if a sample initially contains 100 mg of this isotope, which one of the following correctly gives the amount of the radioisotope remaining after 2 hours have elapsed: none,50mg,25mg,100mg... Etc. Questions like these and harder will be on the test like drawing graphs etc.

Thank you.

Hi,
Radiation detection and measurement by Knoll may be suitable for you.., But it dosen't cover all you need.
 
Sorry, I don't want Books, I want information that i can get on the net. I just want websites that will first teach me the basics and I might be able to catch up from there. Thank you.
 
aha,
there are lot...Just google with keyword..
i often see in this:
http://hps.org/publicinformation/ate/cat47.html
But regarding exposure calculation..it is better to refer books, because in have seen in some website with different values
 
Wow Thanks Rajini, Really helped a lot, hope to see more websites ;)
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
