Introduction Ionizing radiation comes from natural (radioactivity and cosmic radiation) or artificial sources. The artificial ionizing radiation, which includes the X-ray and the radioactive isotopes produced in the nuclear reactors, has many applications, notably in the industries, investigation and medicine sectors, turning the health professionals into exposed workers. Case description A case of a 61-year-old women, radiologic technologist in a radiology department in a pediatric hospital, with forty years of ionizing radiation exposure, culminating in retroperitoneal liposarcoma diagnosis, as described. Discussion The exposure to high levels of Ionizing radiation is related to the induction, yet not exclusive, of cancer. Accordingly, to International Agency for Research on Cancer, the exposure to ionizing radiation directly related to an increased risk for sarcomas, squamous cells carcinomas and adenocarcinomas. Conclusion The health protection of the professional health workers exposed to ionizing radiation within the hospital (as a workplace), brings up a major challenge for the occupational health services, which must organize radiological protection programs aiming to minimize the exposure of the health professionals and potential adverse effects directly related to it. Key-words: ionizing radiation, radiological protection, cancer, liposarcoma, occupational health, work medicine.

INTRODUCTION Workplaces are considered by the World Health Organization as one of the priority places for the development of health promotion actions, namely within the scope of work practices and healthy lifestyles (such as healthy eating, the practice of physical activity, prevention of obesity, professional stress, musculoskeletal injuries, among others). MATERIALS AND METHODS A review of guidelines and scientific articles related to health promotion was carried out, namely on physical activity in an occupational context. Pubmed, UpToDate and Clinical Key, World Health Organization and the Direção-Geral da Saúde were used as the main data sources and the research was carried out using the MeSH terms: “physical activity, health promotion, occupational health”. Publications between the year 2000 and 2022 written in English, Portuguese or Spanish were included. OBJECTIVE A review of the current scientific literature on physical activity is carried out in order to contribute to the implementation and improvement of policies aimed at promoting health in the workplace, thus increasing its potential benefits. DISCUSSION In light of new scientific evidence, all physical activity, regardless of the continuous duration of each practice period, has positive health effects. This implies an adaptation in the way of communicating about physical activity and in the way it is perceived, naturally translating a greater flexibility of behaviors and the potential for their integration, in different moments and contexts. CONCLUSION The recent characterization of physical activity as something easy to integrate into everyday life, regardless of its duration, brings a new vision in the approach to promoting physical activity, imposing the adaptation of strategies and policies that promote this área, namely at occupational level. KEY-WORDS: physical activity, health promotion, public health, occupational health, prevention, work.

Introduction Contact dermatitis comprises 70–90% of all occupational skin diseases, leading frequently to functional disability. If contact dermatitis is suspected, the patient’s occupational history can guide the clinical suspicion as well as the allergens to be tested. Case Report A 63-year-old male electrician, who went to a Dermatology Specialist with pruritic erythematous-scaly lesions on the hands and feet, two years after the onset of symptoms. An epicutaneous test was performed, and Potassium Dichromate, Paraphenylenediamine, Lanolin Alcohols and Textile Blends were found positive. Considering the characteristics of the lesions, their distribution, occupational exposure and the results of skin patch tests, the diagnosis of Allergic Contact Dermatitis was established. Discussion It was possible to establish a relationship between the Personal Protective Equipment used by the worker and the symptoms, as well as establish the presumptive diagnosis of Occupational Dermatitis. The best approach for treatment is to identify and remove the agent, since avoiding the allergens can improve the clinical condition. Workplace analysis, as well as the development of preventive strategies are essential for Occupational Health. It is important to encourage companies to reduce/eliminate exposure to risk factors, promoting the health and safety of workers. Conclusion Contact Dermatitis is associated with a high personal and professional impacts, which can result in absenteeism, reduced productivity and disability. The Occupational Health Care Physician plays an active role in informing workers, with regards to safe working practices and the correct use of Personal Protective Equipment, so that these are used for protection instead of the source of the illness.
