In order to increase comprehensibility, the International Atomic Energy Agency (IAEA) introduced a supplementary warning sign in 2007, which is defined in ISO 21482 \u201cIonizing-radiation warning \u2014 Supplementary symbol\u201d. This symbol combines the traditional warning sign with additional elements such as a skull and crossbones and escape arrows to communicate the danger more clearly. It is intended to be placed directly on dangerous radiation sources to warn laypersons of the potential danger.[\/vc_column_text][\/vc_column_inner][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][divider line_type=”No Line” custom_height=”30″][image_with_animation image_url=”4791″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][vc_column_text css=”” text_direction=”default”]\n

However, the result is somewhat special:<\/p>\n Due to the size of the graphic elements, it would be difficult for the safety sign to pass a visual quality test in according to ISO 9186-2 (Graphical symbols \u2014 Test methods \u2014 Part 2: Method for testing perceptual quality), in which elements of safety signs measuring 50 x 50 mm must be correctly and completely recognized and described by 90% of the respondents at a distance of 2 m. <\/div>[\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]The creators of the ISO 21482 safety sign were obviously aware of this, as the standard emphasizes that the safety symbol W003 from ISO 7010 \u201cWarning of radioactive substances or ionizing radiation\u201d should not be replaced and that the additional safety sign should be placed directly on the very small radiation sources and under a possible device cover. This puts the viewing distance into perspective from an application perspective, but is paradoxical from a hazard perspective; a large distance is essential, but this can only be recognized at a short distance.[\/vc_column_text][\/vc_column_inner][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/2″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”4787″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” img_link_large=”yes” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][vc_column_text css=”” text_direction=”default”]\n Test arrangement according to ISO 9186-2<\/em><\/p>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]The safety sign was tested together with other variants by the Gallup<\/a>Organization (www.gallup.com ) in 11 countries (Brazil, Mexico, Morocco, Kenya, Saudi Arabia, China, India, Thailand, Poland, Ukraine and the USA) with a total of 1650 participants. The test results<\/a> and test method are not public. What is known, however, is that a danger was always detected, but not the type of danger. The \u201cskull\u201d element was the strongest message. Surprisingly, the test results showed no significant differences in terms of culture, gender, age and education.\u00a0Gallup is one of the world’s leading market and opinion research institutes and will certainly have used professional methods, but only tests in accordance with the ISO 9186 series provide the opportunity to evaluate results.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][nectar_cta btn_style=”see-through” heading_tag=”h6″ button_color=”default” text_color=”#b52827″ button_border_thickness=”0px” link_type=”regular” alignment=”left” alignment_tablet=”default” alignment_phone=”default” display=”block” display_tablet=”inherit” display_phone=”inherit” link_text=”Testing symbols” url=”https:\/\/www.bravecroc.de\/en\/sicherheitszeichen-pruefmethoden\/” margin_top=”20″][divider line_type=”No Line” custom_height=”30″][\/vc_column_inner][\/vc_row_inner][vc_row_inner column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]\n Warnings of dangers should and must last as long as possible. In this case, long-lasting means durable and comprehensible for a long time. In the context of radioactive radiation, we are talking about 20,000 to 5,000,000 years, depending on which national authority is responsible. If we assume about 5,000 years of human cultural history, it is no longer important whether the time periods are standards-based or not, it is only a matter of setting or hoping for a minimum chance of comprehensibility. That is the core of atomic semiotics.<\/p>\n In this context, the non-conformance to standardized conventions for the safety sign \u201cIonizing-radiation warning \u2014 Supplementary symbol\u201c according to ISO 21482 is irrelevant.[\/vc_column_text][vc_column_text css=”” text_direction=”default”]\n Safety signs according to ISO 361 and ISO 21482<\/p>\n Symbols \u201eIonizing radiation symbol\u201c as CSL<\/a> Symbols \u201eIonizing radiation symbol\u201c as PDF<\/a>\n
