I want to talk about previous researches related to the impact of cell phone radiation. However, I was not very successful in finding proper verbs to construct such sentences. For instance, I wrote
- There are several works† dedicated to the investigation of harmful effect of cell phone radiation.
- There are several works devoted to the investigation of harmful effect of cell phone radiation.
- There are several works contributed to the investigation of harmful effect of cell phone radiation.
- There are several works focused on the investigation of harmful effect of cell phone radiation.
Personally, I want to use words similar to "dedicate" or "devote" because they have a connotation of strong commitment, perverse attitude or being completely focused on a subject. However, I am not sure about using "dedicate" in such context.
With this regard,
- Does the two first sentences sound natural, especially in terms of using "dedicate" or "devote"?
- If so, is there any synonym for the verb "dedicate" in this context?
† works includes books, articles, journals, and any kind of research papers.
