Opis:
Przedstawiono zgodne z rekomendacjami Międzynarodowej Komisji Ochrony Radiologicznej współczesne standardy ochrony radiologicznej i ich ewolucję na przestrzeni lat na podstawie nowej wiedzy na temat skutków biologicznych działania promieniowania jonizującego oraz zmieniający się stosunek do akceptowanego ryzyka. W pracy w sposób szczególny uwzględniono rolę zasady limitowania dawek i pomiarów dawek indywidualnych w działaniach ukierunkowanych na profilaktykę zdrowotną indywidualnych osób narażonych zawodowo na promieniowanie jonizujące.
The paper presents the current radiation protection standards, in line with the recommendations of the International Commission on Radiological Protection (ICRP), and their evolution over the years based on new knowledge about the biological effects of ionizing radiation and the changing attitude of people to the accepted risk. The work takes into account in particular the role of the dose limit principle and individual dose measurements in activities aimed at health prevention of individual people occupationally exposed to ionizing radiation.

Opis:
Objectives Interventional cardiologists (ICs) are occupationally exposed to low or moderate doses of ionizing radiation from repeated exposures. It is not clear whether these occupational conditions may affect their eye lens. Therefore, the risk of radiation-induced cataract in the cohort of Polish interventional cardiologists is analyzed in this paper. Material and Methods The study group consisted of 69 interventional cardiologists and 78 control individuals occupationally unexposed to ionizing radiation. The eye lens opacities were examined using a slit camera and evaluated with Lens Opacities Grading System III. Cumulative eye lens doses were estimated retrospectively using a questionnaire including data on occupational history. Results The average cumulative dose to the left and right eye lens of the ICs was 224 mSv and 85 mSv, respectively. Nuclear opalescence and nuclear color opacities in the most exposed left eye were found in 38% of the ICS for both types, and in 47% and 42% of the controls, respectively. Cortical opacities were found in 25% of the ICS and 29% of the controls. Posterior subcapsular opacities were rare: about 7% in the ICs group and 6% in the control group. Overall, there was some, but statistically insignificant, increase in the risk for opacity in the ICs group, relative to the control group, after adjusting for the subjects’ age, gender, smoking status and medical exposure (adjusted OR = 1.47, 95% CI: 0.62–3.59 for the pooled “any-eye any-type” opacity). There was also no evidence for an increased opacity risk with an increase in the dose. Conclusions The study found no statistically significant evidence against the hypothesis that the risk of cataract in the group of the ICs occupationally exposed to low doses of ionizing radiation is the same as in the control group. Nevertheless, the adverse effect of ionizing radiation still cannot be excluded due to a relatively small study sample size. Int J Occup Med Environ Health. 2019;32(5):663–75

Opis:
Objectives Mammographic density (MD) refers to the percentage of dense tissue of an entire breast and was proposed to be used as a surrogate marker for breast cancer. High-dose ionizing radiation (IR) has been recognized as a breast cancer risk factor. The aim of our study was to investigate association between lifetime low dose ionizing radiation (LDIR) and MD. Material and Methods A cross-sectional study included 467 women aged 40–60 years who underwent screening mammography in Łódź, Poland. The digital mammography examination of the breasts included both craniocaudal and mediolateral oblique views. The volumetric breast density (VBD) (%) and fibrograndular tissue volume (FG) (cm3) were determined based on the analysis of mammographic image (“for processing”) using Volpara Imaging Software. The exposure to IR was estimated for each individual, based on the data from interviews about diagnostic or therapeutic medical procedures performed in the area of the neck, chest, abdomen and spine, which involved X-rays and γ rays and the data about the doses derived from literature. Linear and logistic regression were fitted with VBD and FG as the outcomes and organ breast dose, effective dose and number of mammographies as the determinants, adjusted for major confounders. Results The analyses showed no association between VBD or FG and the breast organ dose or the effective dose. The only significant finding observed concerned the association between the number of mammographies and the FG volume with β coefficient: 0.028 (95% CI: 0.012–0.043), and predicted mean FG volume >13.4 cm3 among the women with >3 mammographies when compared to those with none. Conclusions This study does not, in general, provide support for the positive association between LDIR and MD. The weak association of the FG volume with the number of mammographies warrants further verification in larger independent studies.

Opis:
Objectives The study aim was to analyse the influence of the lead free cap on doses received by interventional cardiologists. The impact of lead free cap on doses to the head were evaluated in number of studies. As different methods used to assess the attenuation properties of protective cap can lead to ambiguous results, a detailed study was performed. Material and Methods The effectiveness of a lead free cap in reducing the doses to the skin was assessed in clinic by performing measurements with thermoluminescent dosimeters attached inside and outside the cap first during individual coronary angiography (CA) or CA/percutaneous transluminal coronary angioplasty (CA/PTCA) procedures and then cumulated during few procedures of the same type. In order to investigate the effect of the cap on reducing the doses to the brain additional measurements were performed with a male Alderson Rando and polymethyl methacrylate (PMMA) phantoms representing the physician and the patient, respectively for different projections. The brain dose per procedure, annual and cumulated during entire working practice were estimated for both cases working with and without the cap. Results The dose reduction factor (RF) for the skin (the quotient of doses outside and inside the cap) vary from 1.1 up to 4.0 in clinical conditions; on average 2.3-fold reduction is observed in the most exposed left temple. The RFs determined for the part of the head covered by the cap range from 1.4 to 1.8 while for the brain from 1.0 to 1.1 depending on the projection. The estimated annual brain dose for interventional cardiologist performing yearly 550 CA/PTCA procedures without any protective shields is 7.2 mGy and it is reduced with the lead free cap by an average factor of 1.1. Conclusions The study results proved the considerable effectiveness of lead free cap to protect the skin but very limited to protect the brain.
