John Charles Steele (1934-2022) byl kanadský neurolog, který spolu s Richardsonem a Olszewskim popsal novou nozologickou jednotku, které byla původně pojmenována eponymně, časem se ale ujalo označení progresivní supranukleární paralýza. Později se věnoval epidemiologickému a klinickému výzkumu endemického onemocnění amyotrofická laterální skleróza - parkinsonismus - demence komplex z ostrova Guam, zdokumentoval jeho výskyt, fenotypy, klinickou manifestaci, dědičnost a klesající incidenci i prevalenci. Zabýval se taktéž patofyziologií tohoto onemocnění, a řadu let zastával názor, že se jedná o hereditární polygenní onemocnění; až ke konci života přijal hypotézu, která manifestaci nemoci přisuzovala chronické intoxikaci neurotoxickými sloučeninami obsaženými v cykasových plodech: beta-methylamino-L-alanin (BMAA) a metylazoxymetanol (MAM).
John Charles Steele (1934-2022) was a Canadian neurologist who, together with Richardson and Olszewski, described a new nosological entity that was originally named eponymously; however, over time, it became known as progressive supranuclear palsy. Later, he was concerned with epidemiological and clinical research on the endemic disease of amyotrophic lateral sclerosis-parkinsonism-dementia complex of Guam, documenting its occurrence, phenotypes, clinical manifestations, heredity, and decreasing incidence as well as prevalence. He also studied the pathophysiology of this disease, for years holding the view that it was a hereditary polygenic disease; it was only at the end of his life that he accepted the hypothesis which attributed the manifestation of the disease to chronic intoxication with neurotoxic compounds contained in cycad fruits: beta-methylamino-L-alanine (BMAA) and methylazoxymethanol (MAM).

PURPOSE: Over the last decade or so, ethical and societal aspects of radiological protection have received increasing attention. This is also reflected in the publications of the International Commission on Radiological Protection (ICRP). The current paper aims at identifying relevant ethical and societal topics which should receive attention in the context of radiological protection for offspring and next generations. MATERIALS AND METHODS: We present a non-comprehensive review of the subject, based on presentation made at an ICRP workshop in Budapest in 2022. We first discuss the ethical values promoted by ICRP, and the application of these values in cases of (potential) pre-conceptual and prenatal radiation exposures. We then consider experience gained after the Fukushima accident indicating particular societal concerns about the health effects of such exposures. RESULTS AND CONCLUSIONS: Beneficence/non-maleficence, prudence, justice and dignity, the "core values" of the system of radiological protection have special roles to play when heritable and/or in utero effects are to be considered. Prudence, in particular, must be taken account of in view of the fact that solid scientific data in humans are largely lacking in this area, and it is necessary to rely on insights from animal experiments as well as theoretical considerations. As regards societal considerations, the perception of risk among (potentially) affected populations needs to be taken seriously. Accountability, transparency, and inclusivity, the "procedural values" promoted by ICRP for the practical implementation of the system of radiological protection play a central role in overcoming skepticism and creating trust. Stakeholder involvement should emphasize cooperation and dialogue, which allows for the joint evaluation of an exposure situation by experts and affected people.
