Investigation of radiation effects in carbon nanotubes is due to the improvement and addition of their properties during radiation exposure and high technological capabilities. Insensitive radiation causes not only radiation damage in materials, but it can serve as an effective technological tool for creating defects to improve the quality and obtain materials with fundamentally new properties. Electron irradiation of CNT at room temperature is manifested as a result of the formation of vacancies on their walls and, eventually, amorphization at high doses of radiation, multywall CNT are more stable to radiation irradiation than the singlewall CNT, probably because the atoms are cut out of the inner membranes, remain in MCNT. 
The effect of γ and β irradiation ещ the properties of an array of CNT was investigated.

 The figures show the dependences of the coefficient of thermoelectric power and electrical conductivity on the radiation dose for an array of CNTs irradiated with γ and e: it is clear that γ irradiation is more influence on the presented parameters.
