Scattered radiation dose to caregivers’ in plain radiography: a case study

In radiography it is imperative to protect patients and their caregivers from adverse effects of x- radiation when they undergo diagnostic procedures. However, in certain circumstances some radiation practitioners ignore radiation protection measures that should be practiced during x-ray examination...
