The present invention relates to metallated or unmetallated porphyrin derivatives which have varying amphiphilic properties and which may be bonded to polymers, and to processes of their preparation. The present invention further relates to photosensitizers comprising said porphyrin derivatives, and to the use of said photosensitizers for the catalytic formation of singlet oxygen.

The invention relates to a radiation dosimeter comprising a sensor arranged in a dosimeter casing and including at least one measuring field and a calibrating zone (64). To provide a dosimeter which can be readily manufactured and comprises a wide measuring range with high precision, it is provided, according to the invention, that the calibrating zone (64) of the sensor (56) is inserted into a radiation-shielded clearance (66) of a double-wall element (68) being formed by folding a radiation-proof web-like material.
