Instructions for use

Always make sure there is no unprotected area between the thyroid shield and the apron since the thyroid gland is particularly sensitive to ionizing radiation.

Once a month, visually check for possible damage (tears/ cracks). Once a year, take a radiograph of the collar. In the event of radiation signs via cracks in the lead, the collar is porous and must be replaced.


  • Clean with cold soapy water (neutral soap) with a damp cloth, rinse and let dry away from sunlight.
  • Disinfect if needed with a 0.25 % detergent-disinfectant solution for surfaces (i.e. 20 ml = 1 sachet = 1 stroke of dosing pump for 8 l water). Do not rinse (contact time must be 15 minutes minimum and the product is not corrosive).
  • Do not machine wash, do not dry-clean, do not iron, do not sterilize by steam autoclave.
