PPE intended to provide complete user protection against external irradiation or, failing this, adequate attenuation thereof, must be designed to counter only weak electron (e.g. beta) or weak photon (e.g. X, gamma) radiation.
Caithfear TCP atá ceaptha cosaint iomlán a thabhairt d'úsáideoir ar ionradaíocht sheachtrach, nó mura féidir sin, ar mhaolú imleor, a dhearadh chun dul i ngleic le radaíocht lagleictreoin (e.g. beta) nó lagfhótóin (e.g. X, gáma).
