[Thermographically visualized cutaneous reactions after irradiation with fast electrons (author's transl)]. 1979

J Kramer, and H Wendhausen

A comparison was made between thermographically visualized cutaneous reactions of two groups of patients after a therapy with fast electrons. One group underwent one-series irradiation, the other group received two series with an interval of 21 days. The cutaneous reaction after the interval only appeared following considerably higher doses than with one-series therapy. This difference indicates the recuperative capability of normal tissue after the exposition to subtolerance effects. The data were evaluated using a function derived from the Ellis-formula. A "biological dosimeter" can be developed based on thermic reactions of subcutaneous connective tissue.

D008433	Mathematics	The deductive study of shape, quantity, and dependence. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)	Mathematic
D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D004583	Electrons	Stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called CATHODE RAYS.

D013817	Thermography	Imaging the temperatures in a material, or in the body or an organ. Imaging is based on self-emanating infrared radiation (HEAT WAVES), or on changes in properties of the material or tissue that vary with temperature, such as ELASTICITY; MAGNETIC FIELD; or LUMINESCENCE.
