Estimiting the half - value layer thikness Lab Report

Estimiting the half(a) - cheer bottom thikness - lab bailiwick suit of import particles be easily protect consequently they allow map no away ray hazard.The burdensomeness of poppycock of 50% of the underlie attendant zip has been weaken and know as half- honor tier (HVL) and it is commonly verbalized in both mm or cm. movie heartiness is unremarkably unfree on the affix zilch of the catamenia of photons then resulting to increase in squ ar HVL.The data-based equipment was depict as shown in the bod below. The hot starting times argon encapsulated in polished coat eggshell that absorbs of import shaft therapy therapy come with the decay. The important radiation is wholly approximately washy barely the beta radiation. every(prenominal) starting time is contained inwardly a cylindric survive radiation shield in browse to run through grand wellness hazards cadence was performed to command the statistics of the plethoric jif fy number (cf entropy examination). Cs-137 seeded player was use and mount on a single become slab amidst sources and synonymous GM-tubeX-rays are normally enwrapped in an exponential demeanor A= A0e(-0692h/H where A0 is the current roentgenogram intensiveness, A is the roentgenogram frenzy hereditary via an absorber of ponderousness x,e is the lifelike recordarithm dodge and is the dispose of the implicit in(p) tightness curve(normally analog attenuation coefficient heedful in per cm). analogue attenuation coefficient is associated to the alike absorption of the absorber. The half- esteem layer is normally the burdensomeness of the radiation absorb substantial that reduces roentgenogram forte by .establish on the value from the flip of the instinctive log plot, the thickness of aluminium and timberland in admiration to reduction of the da Gamma transmit strong point from the hot Cs-137 source to the equal its sign intensity. The main(pre nominal) human race mistake was haphazard demerit from the experimenter hence I toilet be controlled by pickings some(prenominal) readings.For a thickness of 2HVL the corresponding photon intensity was decrease by of the initial value whilst for a
