Dosimetry with solid thermoluminescence detectors for photon and electron radiations in radiotherapy (ISO 28057:2014)

ISO 28057:2014 describes rules for the procedures, applications, and systems of thermoluminescence dosimetry (TLD) for dose measurements according to the probe method. It is particularly applicable to solid "TL detectors", i.e. rods, chips, and microcubes, made from LiF:Mg,Ti or LiF:Mg,Cu,P in crystalline or polycrystalline form. The probe method encompasses the arrangement, particularly in a water phantom or in a tissue-equivalent phantom, of single TL detectors or of "TL probes", i.e. sets of TL detectors arranged in thin-walled polymethyl methacrylate (PMMA) casings.
The purpose of these rules is to guarantee the reliability and the accuracy indispensable in clinical dosimetry when applied on or in the patient or phantom. ISO 28057:2014 applies to dosimetry in teletherapy with both photon radiation from 20 keV to 50 MeV and electron radiation from 4 MeV to 25 MeV, as well as in brachytherapy with photon-emitting radionuclides. These applications are complementary to the use of ionization chambers.

Dosimetrie mit Festkörper - Thermolumineszenzdetektoren für Photonen- und Elektronenstrahlung in der Strahlentherapie (ISO 28057:2014)

In der vorliegenden Internationalen Norm werden Regeln für die Verfahren, Anwendungen und Messsysteme der Thermolumineszenzdosimetrie (TL-Dosimetrie, TLD) für Dosismessungen nach der Sondenmethode festgelegt. Sie ist anzuwenden insbesondere für Thermolumineszenz-Detektoren fester Form und Größe, d. h. Stäbchen, Scheibchen und Mikrowürfel, hergestellt aus LiF:Mg,Ti oder LiF:Mg,Cu,P in kristalliner oder polykristalliner Form. Sieist nicht anzuwenden für LiF in Pulverform; dessen Gebrauch erfordert spezielle Verfahren. Die Sondenmethode beruht darauf, dass einzelne TL-Detektoren oder TL-Sonden, d.h. Sätzen von TL-Detektoren,  in ein Wasserphantom oder ein wasseräquivalentes Phantom eingebracht werden. Als TL-Sonde bezeichnet man die Anordnung eines oder mehrerer TL-Detektoren in einem dünnwandigen Polymethylmethacrylat (PMMA)-Gehäuse.
Das Ziel dieser Regeln ist es, die Zuverlässigkeit und Genauigkeit zu gewährleisten, die in der klinischen Dosimetrie bei der Anwendung am oder im Patienten oder Phantom unabdingbar sind. Diese Internationale Norm ist anzuwenden für die Dosimetrie in der Teletherapie mit Photonenstrahlung von 20 keV bis 50 MeV und mit Elektronenstrahlung von 4 MeV bis 25 MeV sowie in der Brachytherapie mit Photonen emittierenden Radionukliden. Die TL-Dosimetrie stellt eine wichtige Ergänzung zur Dosimetrie mit Ionisationskammern dar.

Dosimétrie avec détecteurs de thermolumiscence solides pour le photon et rayonnements d'électron en radiothérapie (ISO 28057:2014)

L'ISO 28057:2014 décrit les règles pour les procédures, applications et systèmes de dosimétrie par thermoluminescence (TLD) pour les mesurages de doses conformément à la technique de la sonde. Elle s'applique en particulier aux «détecteurs TL» solides, à savoir les bâtonnets, les pastilles et les microcubes fabriqués à partir de LiF:Mg,Ti ou de LiF:Mg,Cu,P sous forme cristalline ou polycristalline. Elle ne s'applique pas aux poudres de LiF, étant donné que leur utilisation requiert des procédures spéciales. La technique de la sonde comprend la disposition, en particulier dans un fantôme d'eau ou dans un fantôme équivalant à un tissu, de détecteurs TL uniques ou de «sondes TL», c'est-à-dire des ensembles de détecteurs TL disposés dans des boîtiers de poly(méthacrylate de méthyle) (PMMA) à paroi fine.

Dozimetrija s trdnimi termoluminiscenčnimi zaznavali pri fotonskih in elektronskih sevanjih v radioterapiji (ISO 28057:2014)

ISO 28057:2014 opisuje pravila za postopke, načine uporabe in sisteme termoluminiscenčne dozimetrije (TLD) za merjenje odmerkov glede na metodo s sondo. Uporablja se zlasti za trdna »zaznavala TL«, tj. palice, čipe in mikrokocke iz LiF: Mg, Ti ali LiF: Mg, Cu, P v kristalni ali polikristalni obliki. Metoda s sondo zajema razporeditev (zlasti v vodnem ali tkivu enakovrednem fantomu) enojnih zaznaval TL ali »sond TL«, tj. sklopov zaznaval TL, ki so razporejeni v ohišja iz polimetilmetakrilata (PMMA) s tanko steno.
Namen teh pravil je zagotavljanje nepogrešljive zanesljivosti in natančnosti v klinični dozimetriji pri uporabi pri/v bolniku/fantomu. ISO 28057:2014 se uporablja za dozimetrijo pri teleterapiji s fotonskim sevanjem od 20 keV do 50 MeV in elektronskim sevanjem od 4 MeV do 25 MeV ter pri brahiterapiji z radionuklidi, ki oddajajo fotone. Ti načini uporabe dopolnjujejo uporabo ionizacijskih komor.
