Abstract

The proposal is for a novel, simple, reversible actinometer for measuring the solar radiation in the erythema-active u/v-B range between 280 and 320 nm based on the combination of a phototropic material (glass or plastic) with a filter which is transparent in the u/v-B and visible spectra but selectively masks out the intermediate u/v-A range which thus does not affect the indication. As an alternative to the combination of a phototropic material and a selective filter layer it is also possible to use a coloured layer or plastic which selectively discolours under u/v-B radiation as the indication field. Advantages of the actinometer of the invention include the fact that it can be used repeatedly, its rapid and adequately accurate indication, its passive mode of operation and its low price. Such an actinometer allows the user to read off the intensity of the u/v-B radiation at any time, relate it to further relevant data, e.g. the type of skin and the protection factor of the product used, find the still safe exposure time and thus prevent the occurrence of sunburn and resultant skin lesions.

Description

Meßeinrichtung für die UV-B-Strahlungsleistung im Sonnenlicht.Measuring device for the UV-B radiation power in sunlight.
Die Erfindung bezieht sich auf eine Meßeinrichtung für die Erfassung der UV-B-Strahlungsleistung im Sonnenlicht.The invention relates to a measuring device for detecting the UV-B radiation power in sunlight.
Meßgeräte für diesen Anwendungszweck sind seit vielen Jahren bekannt und werden z. B. im Zusammenhang mit der allgemeinen Wetterbeobachtung, in den letzten Jahren zunehmend auch ausschließlich mit der Zielsetzung der kontinuierlichen Beobachtung des UV-Spektrums, eingesetzt.Measuring devices for this application have been known for many years and are used, for. B. in connection with general weather observation, in recent years increasingly used exclusively with the objective of continuous observation of the UV spectrum.
Diese Geräte sind sehr aufwendig konstruiert, da sie des wissenschaft¬ lichen Einsatzes wegen kalibrierfähig sein sollen. Dementsprechend sind sie auch nicht unbeschränkt transportabel und sehr teuer. Ein¬ fache, zuverlässige und billige Meßeinrichtungen, mit deren Hilfe jeder Benutzer zu jeder Zeit die UV-B-Strahlungsleistung genügend genau bestimmen kann, um daraus gesundheitlich relevante Daten abzu¬ leiten, existieren nicht.These devices are designed to be very complex since they should be capable of being calibrated for scientific use. Accordingly, they are not transportable without restrictions and are very expensive. There are no simple, reliable and inexpensive measuring devices with the aid of which each user can determine the UV-B radiation power with sufficient accuracy at any time in order to derive health-relevant data therefrom.
Mehrere elektronische Geräte, die auf dem Markt sind bzw. waren, messen entweder den UV-A-Bereich, den Infrarot-Bereich, oder die bereits be¬ stehende Bräunung der Haut. Alle 3 Verfahren sind, da sie nicht die Strahlungsleistung im UV-B-Bereich messen, nicht für die Erfüllung der erfindungsgemäßen Aufgabe geeignet, da eine Korrelation zwischen UV-B-Strahlungsleistung der Sonne und deren UV-A-Strahlungsleistung wegen der unterschiedlichen Beeinflussung durch die ständig wechselnden atmosphärischen Einflüsse nicht möglich ist, noch weniger eine Korrelation zwischen der UV-B-Strahlungsleistung und der Infrarot- Strahlungsleistung.Several electronic devices that are or were on the market either measure the UV-A range, the infrared range or the already existing tanning of the skin. All 3 methods, since they do not measure the radiation power in the UV-B range, are not suitable for fulfilling the task according to the invention, since there is a correlation between the UV-B radiation power of the sun and its UV-A radiation power due to the different influences by the constantly changing atmospheric influences is not possible, still less a correlation between the UV-B radiation power and the infrared radiation power.
Weiterhin gibt es Karten, deren Indikatorfelder nur einmal durch Verfärbung auf Sonnenbestrahlung reagieren können. Bei diesen ist aber weder der relevante Spektralbereich noch die zu einer bestimm¬ ten Strahlungsleistung gehörende Verfärbung zu ermitteln. Der bekannte derzeitige Stand der Technik bei passiven UV-B-Indikatoren ist durch die Gebrauchsmuster DE - G 89 13 728.0 und DE - G 91 00010.6 gegeben.There are also maps whose indicator fields can only react once to sun radiation by discoloration. With these, however, neither the relevant spectral range nor the discoloration associated with a particular radiation power can be determined. The known current state of the art for passive UV-B indicators is given by the utility models DE - G 89 13 728.0 and DE - G 91 00010.6.
Der Erfindung liegt die Aufgabe zugrunde, eine einfache Meßeinrichtung zu schaffen, die, in Anbetracht des gefährlichen, sich gegenwärtig noch beschleunigenden Rückgangs der alle Lebewesen vor Sonnenstrahlung im UV-Bereich schützenden Ozonschicht, die Stärke der aufgenommenen UV-B-Strahlungsleistung (als dem wesentlich gesundheitsgefährdenden Anteil) festzustellen.The invention has for its object to provide a simple measuring device which, in view of the dangerous, currently accelerating decline of the ozone layer protecting all living beings from solar radiation in the UV range, the strength of the absorbed UV-B radiation power (as the essential health-endangering proportion).
Aus dem aktuellen Meßergebnis kann dann der Benutzer mit Hilfe einer aufgedruckten oder mitgelieferten Hauttyp-Vergleichstabelle ableiten, welche Bestrahlungszeit bei ungeschützter Haut maximal zu verant- orten ist, bevor die Gefahr eines Sonnenbrandes (und damit von un¬ kalkulierbaren Hautschäden einschl. Hautkrebs) gegeben ist. Diese Angäbe ermöglicht es dem Benutzer, sein Risiko zu minimieren, wobei weitere relevante Werte, wie z. B. der Schutzfaktor eines aufgetra¬ genen Sonnenschutzmittels oder die Anzahl der kurz hintereinander genommenen Sonnenbäder, mit berücksichtigt werden können.The user can then use the printed or supplied skin type comparison table to derive from the current measurement result the maximum exposure time for unprotected skin before there is a risk of sunburn (and thus of incalculable skin damage including skin cancer) . This information enables the user to minimize his risk, while other relevant values, such as. B. the protection factor of an applied sunscreen or the number of sunbaths taken in quick succession can also be taken into account.
Erreicht wird dieses Ziel dadurch, daß eine, in einem Träger unter¬ gebrachte, aus Glas oder Kunststoff bestehende Scheibe oder Fläche mit einem Pigment dotiert ist, welches beim Auftreffen von UV-B-Strahlung sich entweder verdunkelt oder seinen Farbton ändert. Nach einer material¬ abhängigen Bestrahlungszeit hat die Verdunkelung bzw. Verfärbung einen Endwert (Sättigung) erreicht und kann nun mit einem daneben ange¬ brachten Vergleichsfeld (Grautreppe, Graukeil, Farbtreppe oder Farb¬ verlauf) verglichen werden, wobei der Grad der Veränderung ein Maß für die aktuelle UV-B-Strahlungsleistung darstellt. Gleichermaßen kann dieses Ziel dadurch erreicht werden, daß die Anzeigefläche mit einer Farbe bedruckt wird, deren Pigmente in geeigneter Weise reagieren. Zur Erreichung der angestrebten Anzeigegenauigkeit wird es erforderlich sein, daß die Anzeigefläche oder eine Abdeckung derselben mit einem UV-A-Sperrfilter versehen wird, falls nicht das Material der Anzeige¬ fläche von sich aus UV-B-selektiv ist. Eine erfindungsgemäße Meßeinrichtung für die UV-B-Strahlungsleistung im Sonnenlicht, die z. B. als Ansteckbutton, Anhänger, Schmuckstück oder im Scheckkartenformat (siehe Zeichnung) ausgeführt werden kann, läßt sich sehr preiswert herstellen.This goal is achieved in that a pane or surface, which is accommodated in a support and is made of glass or plastic, is doped with a pigment which either darkens or changes its color when UV-B radiation is incident. After a material-dependent irradiation time, the darkening or discoloration has reached a final value (saturation) and can now be compared with a comparison field (gray staircase, gray wedge, color staircase or color gradient) attached next to it, the degree of change being a measure of represents the current UV-B radiation power. Likewise, this goal can be achieved by printing on the display surface with a color whose pigments react in a suitable manner. To achieve the desired display accuracy, it will be necessary to provide the display surface or a cover thereof with a UV-A blocking filter, unless the material of the display surface is inherently UV-B selective. A measuring device according to the invention for the UV-B radiation power in sunlight, the z. B. can be carried out as a pin, pendant, piece of jewelry or in credit card format (see drawing), can be produced very inexpensively.
In der Zeichnung einer praktischen Ausführung als Scheckkarte (1), der erfindungsgemäßen Meßeinrichtung, sind neben der Darstellung einer vorteilhaften Anordnung der Anzeigefläche (2) und des hier als Grautreppe ausgeführten Vergleichsfeldes (3), auch die Anzahl der kürzlich genommenen Sonnenbäder (4) und der Schutzfaktor des verwendeten Sonnenschutzmittels (5) berücksichtigt.In the drawing of a practical design as a check card (1), the measuring device according to the invention, in addition to the representation of an advantageous arrangement of the display surface (2) and the comparison field (3) designed here as gray stairs, also the number of recently taken sunbaths (4) and the protection factor of the sunscreen used (5) is taken into account.
Die Beschränkung auf die Anzeige der UV-B-Strahlungsleistung unter gleichzeitiger steilflankiger Ausblendung der UV-A-Strahlungsleistung ist sinnvoll, wenn man auf die Anzeige des vorwiegend kosmetisch wirksamen Teils des Sonnenspektrums zugunsten der reinen Gesundheits¬ vorsorge verzichtet. Nach dem heutigen medizinischen Erkenntnisstand wird diese Lösung von Fachärzten bevorzugt. The restriction to the display of the UV-B radiation power with simultaneous steep-sided suppression of the UV-A radiation power makes sense if one does not display the predominantly cosmetically active part of the sun spectrum in favor of pure health care. According to today's medical knowledge, this solution is preferred by specialists.
