Chloroacetic acid <em>is stronger. </em>
<em>This is because it contains (more electronegative) chlorine atoms in place of (less electronegative) hydrogen atoms.</em>
Alpha decay involves the loss of an alpha particle, aka a helium nucleus. This results in the mass number of the original element decreasing by 4 and the atomic number decreasing by 2. Assuming 23942u is uranium (92), the resulting element's atomic number is 90, making it thorium.
I think it is a radiation poisoning
