>>2260As a Chemistry grad the only advice I can give you is immediately pivot to a more applied sub-field when it comes to getting experience if you actually want to be employable at one point. The classic lab head/synthesis career is dead unless you want to spend a decade in academia and then maybe you might make it in something like drug design. With a Bachelor's and no other experiences there are only badly paid quality assurance/analytics jobs and in (chemical) industry engineering grads are vastly preferred over physical scientists because they can actually build/manage industrial plants.
Unless you don't want to be stuck being a waste water technician at your municipal treatment plant you need to pivot to fields that are a bit removed from classical chemistry such as materials science and engineering (energy materials, metallurgy, plastics, composites, etc. for example), semiconductors, electrochemistry/battery tech or thin film/deposition technology are way more employable than the classical chemistry route and in the areas of the aforementioned areas you are competing with people that have done more adequate majors.
Industry experience is nowadays way more important than virtually anything including what your actual STEM diploma says. If you are set on radiochemistry please for the love of got get one, two or three internships in adjacent industries that deal with it like in radiopharmacy, oncology and medical/clinical imagining or in the nuclear industry if your country has one before you even remotely think about graduating.
