Ionizing Radiation Work
Ionizing Radiation Work
Ionizing radiation is a type of radiation that has enough energy to knock electrons out of atoms or molecules, thereby turning them into charged particles. Ionizing radiation work refers to situations in certain workplaces where employees may be exposed to varying levels of radiation. Therefore, appropriate safety measures must be implemented, such as wearing radiation protective equipment, regularly monitoring radiation levels, establishing protective barriers in radiation areas, and adhering to strict radiation safety regulations and operating procedures.
Health Hazards
Acute:
High energy causes chemical bond breaks, leading to cellular damage and necrosis. The severity of the damage depends on the dose, area, duration, and location of exposure.
The primarily affected tissues include the reproductive, hematopoietic (blood-forming), gastrointestinal, and skin systems, which have rapid metabolic activity.
Exposure above 100 cGy can cause discomfort within 6 hours (fatigue, headache, dehydration, gastrointestinal discomfort, respiratory distress, arrhythmia). Within one week, hematopoietic issues and gastroenteritis may appear.
Those exposed to doses below 600 cGy generally have a good prognosis with appropriate treatment.
Chronic:
Exposure to 80-210 cGy (low dose) can cause hematopoietic problems and gastroenteritis within four weeks.
Chronic complications may include skin lesions, obstructive arteritis, intestinal strictures, pulmonary fibrosis, cataracts, thyroid tumors, and leukemia.
Suggestions:
Level 1 Management: No specific regulations.
Level 2-4 Management:
Consider the unsuitability for workers with conditions such as blood disorders, endocrine disorders, mental and neurological abnormalities, eye diseases, malignant tumors, and protection of pregnant workers' health.
