The aim of this work was to verify the treatment thermal, ultraviolet (UV‐C) and gamma irradiation effect in the weight loss and breathing activity ‘Hass” avocado. After selection, the fruits were submitted to thermal treatment at 45ºC for 5, 10, 15 and 20 minutes. The gamma irradiation concentrations evaluated were of 0.2; 0.4; 0.6 and 1.0 kGy. Fruits were treated with ultraviolet rays (UV‐C =250nm), being the distance of the fruits to the source of light of 20 cm and the period of exhibition of 5, 10, 15, 20 minutes. Along the storage period it happened increase of the weight loss. In the time 12 the irradiated treatment differed of the others for the largest weight loss. The rates breathing, the treatment with irradiation range differentiated of the others for the largest rates breathing under room temperature. It happened increase of them rates breathing to the 9th day of storage for all treatments, being a more pronounced pick observed in the treatment with gamma irradiation. As much the thermal treatment as UV under refrigeration they resulted in a reduction in the breathing pick compared to the witness. In the treatment with gamma irradiation, all the doses presented values of rates breathing superiors the witness. In the treatment UV in general the time of exhibition of 5 minutes was what showed smaller breathing. In the thermal treatment the times were 10 and 15 minutes.
