Le calculateur d\u2019att\u00e9nuation pour le blindage radiologique de NPO vous permet de d\u00e9terminer avec pr\u00e9cision le mat\u00e9riau et l\u2019\u00e9paisseur de blindage requis pour r\u00e9duire l\u2019exposition aux rayonnements ionisants \u00e0 un niveau acceptable.
<\/p>\n

Nos scientifiques chez NPO ont mis \u00e0 profit leur expertise pour d\u00e9velopper cet outil, fournissant des donn\u00e9es d\u2019att\u00e9nuation extr\u00eamement fiables pour une large gamme de mat\u00e9riaux de blindage, y compris la gamme de produits T-Flex de NPO. Cet outil a \u00e9t\u00e9 d\u00e9velopp\u00e9 \u00e0 l\u2019aide du code \u00ab Monte Carlo N-Particle \u00bb (MCNP), un programme de simulation avanc\u00e9 qui mod\u00e9lise l\u2019interaction des rayonnements (gamma, neutroniques, etc.) avec divers mat\u00e9riaux de blindage selon leur composition et leur densit\u00e9.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Les calculs sont bas\u00e9s sur le logiciel de simulation \u00ab Monte Carlo N-Particle \u00bb (MCNP).<\/span><\/li>\n
  2. La configuration \u00ab faible exposition \u00bb correspond \u00e0 une source ponctuelle entour\u00e9e d\u2019un blindage sph\u00e9rique concentrique.<\/span><\/li>\n
  3. La configuration \u00ab forte exposition \u00bb correspond \u00e0 une source \u00e9tendue ( plaque) avec des couches planes de blindage superpos\u00e9es.<\/span><\/li>\n
  4. Conversion de la laine de plomb (couverture souple) en plomb massif \u00e9quivalent – 10 lb\/pi\u00b2 = 0,170 pouces (\\~4,32 mm), 15 lb\/pi\u00b2 = 0,254 pouces (\\~6,45 mm) <\/span><\/li>\n<\/ol>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
