This paper focuses on problems connected with equivalent dose (ED) estimation. The ED results obtained by using two methods: regeneration (R) and total-bleach (TB) were compared. To this end, ten loess samples were taken from about 20 m thick Zahvizdja profile (western Ukraine). The obtained results show that the ED values are strongly dependent on the applied technique. When using the regeneration method, the maximum ED value observed is 1051š158 Gy. The total-bleach procedure gives considerably different results, because the gradual increase of ED values is recorded up to 2833š896 Gy. TL ages obtained by the TB method were confirmed by palaeomagnetic investigations.
