✦ Synopsis

To prevent radioactive surface contamination of solid state detectors for low-level alpha spectrometry, thin plastic foils are used as stopper foils for recoil nuclei. Measurements show that a stopping efficiency of 100% for recoil nuclei may be obtained at the expense of approximately 20% loss of energy resolution (FWHM) for peaks in the resulting spectrum of the source due to straggling of a particles.

## Abstract ## Background and Objectives In the last decade, many different kinds of therapies have emerged as a consequence of advances in the field of applied technology. It is known that low level laser therapy contributes to tissue healing; however, the use of photodynamic therapy (PDT) in hea
