X-ray-guided interventions have increased in number and complexity. Mandatory radiological protection training includes both theoretical and practical training sessions. A recent additional training tool is real-time display dosemeters that give direct feedback to staff on their individual dose rates. Ten staff members who regularly perform pulmonary bronchoscopy wore an extra dosemeter during four 2-month periods. We controlled for the patient air kerma area product and the number of procedures in each period. Between periods 1 and 2, radiological training sessions were held and during period 3 the staff used the real-time display system. Focus-group interviews with the staff were held to obtain their opinion about learning radiological protection. We hypothesised that neither training nor the additional real-time dose rate display alters the personal dose equivalent, Hp(d); d = 0.07 and 10 mm. Useful experiences from radiological protection training were obtained, and median staff doses did decrease, however not significantly.
X 射线引导介入的数量和复杂性不断增加。强制性的放射防护培训包括理论和实践培训课程。最近的一个额外的培训工具是实时显示剂量计，它可以直接向工作人员反馈他们的个人剂量率。十位经常进行肺支气管镜检查的工作人员在四个 2 个月的时间段内佩戴了额外的剂量计。我们在每个时间段内控制患者空气比释动能面积乘积和操作次数。在第 1 阶段和第 2 阶段之间进行了放射防护培训，在第 3 阶段工作人员使用了实时显示系统。对工作人员进行了焦点小组访谈，以了解他们对放射防护学习的看法。我们假设培训和额外的实时剂量率显示都不会改变个人剂量当量 Hp(d)；d=0.07 和 10 毫米。从放射防护培训中获得了有用的经验，工作人员的剂量中位数有所下降，但没有显著变化。
