This study proposes organization of the activity of a radiotherapy service during the pandemic COVID-19 period. Reliable circuits for staff as well as for patients are installed and treatment protocols are adapted to the current COVID-19 situation. Several scenarios are proposed to deal with any subsequent pandemic situation.

The additional cancer risk factor is calculated by the X-ray risk software promoting responsible imaging through patient and provider education. It is function of the effective dose received, the age at the time of exam, and gender of patient. Results: The radiological average effective dose received per act exam is 1 millisievert (mSv), whereas it is 4.45 mSv and 0.21 mSv for the computed tomography (CT) scan and conventional radiological examinations, respectively. As for the average number of acts per patient 2.66, the effective dose is 1.16 mSv and 3.8 mSv for CT scan and conventional radiological examinations, respectively. As for the average effective dose per patient 2.69 mSv, it is 5.16 mSv and 0.81 mSv for CT scan and conventional radiological examinations, respectively. As for the additional cancer risk in 40 years at the time of exam, the average additional cancer risk is equal to 2.17 × 10 -4 , wheras the risk is 4.17 × 10 -4 and 6.54 × 10 -5 for CT scan and conventional radiological examinations, respectively. Conclusion: Medical exposure related to the diagnosis of patients in the radiology service in 2012 can be characterized by: (a) 2.66 Act exams on average per patient diagnosis corresponding to a mean effective dose equal to 2.69 mSv per patient, (b)frequency of conventional radiology and CT scan was 81% and 19%, respectively. These act exams contribute to the collective effective dose by 17% and 83%, respectively, and (c) radiological acts can be divided into three levels of exposures: 0 to 5 mSv, 5 to 10 mSv, and > 5 mSv, and the proportion of each level is 90.12%, 9.84%, and 0.05%, respectively.

We evaluated medical exposure and risk estimation during routine radio-diagnostic examinations in Agadir City during the year 2012. The frequency data were collected from four main Radiological departments of the city performing radiography as well as computed tomography (CT) procedures. The estimated annual number of examinations was approximately 100.000. Eighty percent of diagnostic examinations were conventional radiology procedures while CT exams represent only 20%. The evaluated annual number of examinations was 206 per 1000 people. The estimated annual collective and per inhabitant effective doses from medical X-ray procedures mount 23,207 man Sv and 0.24 mSv, respectively. These results allow us to classify Agadir City at healthcare III according to UNSCEAR classification. As for the average effects during medical exposure, it is 132 10 −7 and 5 10 −7 additional cancer risks and the hereditary effects, respectively. The study presented the first assessment of frequency and population dose from medical expositions in Agadir City and it provides estimates of the impact of the medical x-ray procedures.
