 	    	<li>This graph shows the concentration of infectious quanta in the air. The filtration of Type I and FFP2 masks, if worn, applies not only to the emission rate but also to the individual exposure (i.e. inhalation).
-	    For this reason, scenarios with different types of mask will show the same concentration on the graph but have different Pi values.</li>
+	    For this reason, scenarios with different types of mask will show the same concentration on the graph but have different absorbed doses and infection probabilities.</li>
 	   		<li>If you have selected more sophisticated options, such as HEPA filtration or FFP2 masks, this will be indicated in the plot as the "base scenario", representing the inputs inserted in the form.<br>
 	    	The other alternative scenarios shown for comparison will not include either HEPA filtration or FFP2 masks.</li>
